I know so much more about this topic than I want to. For what it is worth, i developed the problem years ago. Three things I did/do regularly contributed....drumming, carpentry (vibrating sanders and tools in particular) and cycling - (face it, you put a lot of weight on your flexed wrist with most bikes. Even when there isn't weight on the cycle, people often bend their wrist, putting pressure on the median nerve and compressing the carpal tunel....it is a common problem for many after years of no problems). I still do all three things and while my right hand is mostly cured, it is also significantly weakened after a post-surgical fall while healing. My left side still bugs me. every ride I have lead, people ask me what I am doing when I put my left hand behind my back and start flexing my hand....those are my tendon glide exercises! I do them as the problem occurs, and that is just how i live at this point.
I get aches and pains too from cycling (like the one's you're describing) and from my previous job slinging 100's of #'s of bread dough around. My wife's a PT and is always able to find the muscle area that's been overworked (not always in the same spot as where the pain is), and gives me stretches and exercises that within a week or so fix the problem. Her big objection to surgery for muscular skeletal stuff is that the surgeon is going to cause damage going in to the problem area, and then prescribe PT to heal. Why not just get the PT for the problem area in the first place?
And like H3 said - look at your sleep. I'm a side sleeper and it's awful for my neck and shoulders.
Also - I recently had pain in my lower forearm, and a tennis elbow brace above the elbow made it go away. (but note that the brace didn't fix the problem - the stretches and exercises did)
I could post pics of stretches and exercises that have helped me, but I would disclaim that I am merely the husband of a DPT sharing what's worked for me, and should not be taken as serious medical advice or recovery program, etc....
If you're experiencing any ache, pain, or injury, I strongly suggest a face to face examination with a professional for determining a treatment plan.
And remember, just cause we're cyclists, doesn't always mean that the soreness is cycling related. I had some knee pain too - but figured out it was from how I was sitting at my job, not the cycling. Some playing with my desk setup fixed it. My body isn't teenage anymore :(
...and lots of extra strength Tylenol...
