This shoulder pain has been an ongoing issue for me pretty much since I started riding but has become worse in the last couple of years. It's additive, the more I ride the worse it gets. Consecutive days of riding are worse. Harder and hillier rides are worse. The pain is close to the midl ine on the right side of my back and shoulder. It feels very deep. Sometimes the whole shoulder becomes numb when it get really bad. I notice my whole right arm gets slightly sore too. I did a 60 mile ride yesterday on my road bike and today I did a 25 easy recovery ride on my commuter and I could feel the pain in my shoulder returning. I really don't want this to screw up my riding season again this year

I am wondering if I have a muscle imbalance. Oddly my right bicep is significantly larger than my left. I've been considering seeing a PT about this but not sure I want to try that route for fear that it won't help and I'll waste the money.

Any suggestions appreciated.
