“Some cycling ailments are confined to the elite and some to recreational riders. It is unheard of for me to see [...] our national squads with numb or tingling hands. However, I have seen serious recreational cyclists with quite debilitating hand-nerve injuries referred to me by local doctors.”
A good chunk of the book deals with off-bike stretches and flexing to cut down on injuries too. I've found better off-bike care has helped me a lot, and I know a good number of cyclists who swear by their yoga sessions.
Hope your situation improves!
Edit to add: He also has a few videos on Youtube with advice on improving your fit for comfort and pain relief, which is a cheaper option than the book ;)
