Yes, there are reports of trigger points in the jaw muscles being at least partially responsible for tinnitus (see e.g. https://www.amazon.com/Trigger-Point-Therapy-Workbook-Self-T... which, if you have any muscle related pains, will likely blow your mind.) I have exactly the same experience as you. I also get jaw induced headaches from biting my nails etc and my impression is that it is associated with an increase in my tinnitus.

Probably a related mechanism, but I can also sometimes hear my eye muscles working. It only happens if I'm sick or otherwise feeling under the weather, but moving my eyes rapidly is then associated with a swoosh-like auditory impression. I haven't heard anyone else experiencing this so far.

I am currently rehabbing hand pain right now and the number 1 thing that is helping is this book:

The Trigger Point Therapy Workbook: https://www.amazon.com/Trigger-Point-Therapy-Workbook-Self-T...

I believe that the primary cause of my hand pain is my forward head posture. This can create trigger points in the scalene muscles of the neck which cause sattelite trigger points in my forearms (especially the extensor muscles) and in my upper arms as well. These trigger points then refer pain to the hands. Self-massage using a lacrosse ball has pretty much eliminated my pain and seems to significantly increase bloodflow to my hands.

NOTE: be very gentle the first time you do self massage of the scalenes with your fingers. I went too hard and my scalenes swelled up for 3 days and I experienced the symptoms of thoracic outlet syndrome, ie. I had numbness from my collarbone to my middle and ring finger on my left side. It went away once my neck healed.

It definitely seems circulation related: whenever I use a computer with cold hands, it causes tension and then pain. I make sure to never use a computer with cold hands. I recently purchased this Far Infrared heating pad to heat my hands. It really does work a ton better than traditional heating pads with resistive coils. https://www.amazon.com/UTK-Infrared-Electric-Therapy-19-Inch...

Also, it is critical to correct the weakness and structural problems in the body. I do yoga, strength training, and swimming and these seem to be helping keep the trigger points from coming back. I am also doing shoulder mobility exercises with a stick and following this guide to correct my forward head posture: http://posturedirect.com/forward-head-posture-correction/

Oh man, do I feel you on that. Doctors are fairly worthless in my opinion for these issues. I say this having dealt with various RSI/nerve pain issues for over 6 years, and tens of thousands of dollars in out of pocket medical bills. They'll pretty much always be like "just take an Aleve", or "I don't know, do some physical therapy or wait and see if it gets better. Next patient please!". Your health and getting better will be on your shoulders.

With that in mind, I'd like to preface all of the following by saying: I am not a doctor. This information is for educational purposes only, and is not meant to be a substitute for professional medical advice.

----------------------------------------------------------------------------------

Here is a long, varied guide on everything I've learned and things that have helped. Most of my knowledge has come from trial and error, and reading books and medical papers.

I have had tingling, burning pain throughout my arms and hands for many years. I also had several bouts of nerve pain in my legs. RSI and nerve pain stuff seem to go hand in hand. A lot of this advice ties into reducing nerve pain as well. I've had three surgeries total to move my ulnar nerves out of their ulnar tunnel so they would stop snapping over the bone and causing me pain. This wasn't the only cause of my issues though.

A lot of pain in your arms actually originates in your neck/shoulder area. There is an issue called Thoracic Outlet Syndrome that is suspected to be the cause of most of this kind of arm/hand pain. Chances are, you have bad posture.

Things that helped:

- Using a macbook pro for all computer use. Using a mouse or raised keyboard is awful for your hands. The trackpad placement with the keyboard, and the fact you can set the trackpad to register a touch (without pushing down) as a click are very helpful. Make sure you're not bending your wrists to the left or right when typing. It's a hard habit to break, and you're probably doing it now, but ideally you want your hands to be straight in line with your arm. Wrong - https://ehs.okstate.edu/modules/ergo/hand4.gif. Right - https://ehs.okstate.edu/modules/ergo/hand3.gif. Also, don't raise up your hands when typing or using a mouse, it stresses out your forearm muscles.

- No keyboard or mousepad wrist pads, they just constrict the nerve pathways in your wrists.

- You want to make sure your posture is good. When working at a desk, you actually should be sitting back against the seat, with your arms supported by the arm rests. You shouldn't be sitting straight up 90 degrees, but leaning back a little, with your back supported against the chair. This picture kind of shows it - http://cdn.makeuseof.com/wp-content/uploads/2013/06/computer... - though I would say you should be a bit less far back than the 135, maybe like 110.

- General posture stuff: when walking make sure your hips aren't tilted forward or backwards, make sure your shoulders are slouched forward, make sure your head isn't tilted forward (99% chance you do this one and don't even realize). Make sure your shoes' soles aren't worn down - if you see they look uneven buy new shoes.

- TMS (Tension Mytostis Syndrome) - basically is stress and anxiety making your brain subconsciously cause your body pain. Really helpful with me way after my surgeries in getting from 3-4 pain level to 0-1. I read this one - http://www.amazon.com/gp/product/0446675156/ref=pd_lpo_sbs_d....

- The Trigger point therapy workbook - http://www.amazon.com/Trigger-Point-Therapy-Workbook-Self-Tr.... Your muscles get tight and get these things called trigger points. This causes them to tense up and pull on other muscles, starting a bad chain reaction causing pain all over. This will teach you not only how to do trigger point self massage, but how groups of muscles can affect other parts of the body far away from them. You’ll also want to pick up a pair of lacrosse balls, they’re super helpful for self massage.

- OTC pain pills – this I discovered recently – NSAID’s like Aleve work by reducing inflammation, while Tylenol works more on your Central Nervous System by increasing your pain threshold so it takes higher levels of pain before you can feel them. Also way gentler on your stomach than Aleve. Aleve can also cause some damage to your digestive system, making it harder to absorb…

- B12 vitamins – a deficiency of b vitamins, especially 12 can cause neuropathy (nerve pain). This b vitamin combo is really good, has all the best options for each one inside of it - http://www.swansonvitamins.com/swanson-ultra-high-potency-ac...

- Sleep – I find that if I get less than 8 hours of sleep over a period of a few days my nerves start to light up a bit (not sure how else to describe it). Sleep is super important, it’s when your body does most of its repairing and healing.

- Anti anxiety meds – klonopin, xanax, etc - if you can get prescribed these, I’ve found them more helpful than painkillers sometimes, they definitely take the edge off. From what I've read they can be very addictive though, so watch out for that.

- Actual nerve pain medicine – I learned about this reading Wolf of Wall Street. Turned out he had terrible, chronic nerve/back pain that drove him to do all those drugs. He was at the end of his rope, multiple surgeries and still a lot of pain. His doctor ends up prescribing him Lamictal, which at the time was a medicine for seizures, and it’s like a switch was flipped and he wasn’t in pain anymore. There are better options these days for that though, Lyrica is a popular, as is Neurontin. They can have some side effects, but apparently can be very effective (I’ve never tried them myself, was able to get my pain down to a manageable level for the most part, though I do have them in my mind as a back up if it gets really bad again) - http://www.mayoclinic.org/diseases-conditions/peripheral-neu...

If you would like to do more research on top of what I described above:

- If you want to go to a doctor, try a neurologist or a good physical therapist. Most doctors are infuriatingly ignorant and incompetent when it comes to these kinds of issues.

- Read about the nerves in the arm, and thoracic outlet syndrome

Good luck, and try not to lose hope, I know how being in pain every day can wear someone out. Remember that there’s a good chance you won’t be in pain or at least it will be manageable at some point in the future, even if that may be a while out. If you want to ask me any questions, I'd be happy to help.

Obvious question is obvious, but may also be helpful: have you seen a competent psychotherapist?

If the tension is indeed psychosomatic, then treating the psychological cause may be the way to go.

Other things that would be worth investigating: Alexander Technique, Pilates (yes, seriously. What you're describing could be breathing-related in particular, and Pilates is good at that stuff. Go for a teacher accredited by an organisation with a multi-year training program.), Tension Mytosis Syndrome, T'ai Chi (again, seriously. Good t'ai chi can be very useful), trigger point therapy (read http://www.amazon.com/Trigger-Point-Therapy-Workbook-Self-Tr...), deep tissue massage (painful but effective).

I will make my standing recommendation for "The Trigger Point Therapy Workbook" now: http://www.amazon.com/Trigger-Point-Therapy-Workbook-Self-Tr...

A little late to the party, but I went through a bout with wrist/arm pain for over a year. I did physical therapy for more than 6 months, saw a doctor that said I needed to have surgery on my arms, neither helped (did not have surgery BTW). I then finally saw a myofascial specialist. She identified the cause of my pain from trigger points in my upper back and shoulders. After just one visit and a follow up visit a year later, I've been relatively pian free. She basically taught me how to address the trigger points my self using a tennis ball and 'The Trigger Point Therapy Workbook' http://www.amazon.com/Trigger-Point-Therapy-Workbook-Self-Tr...

I'd definitely give this book a try since it clearly identifies which trigger points are causing the referred pain/numbness along with the ways to treat them.
