Im hoping someone could give me some advice. I have recently been developing injuries or pain gradually after climbing. I warm up and stretch before I climb and feel fine generally whilst climbing yet directly afterwards or during the end of my session I am experiencing severer pain in my left shoulder. It has progressively got worse and I have also had a similar experience in my left wrist- aching and stiff. There has been nothing that I have done that has caused me to stop and go ow I have hurt myself, it comes on like a headache and effects my whole arm into my elbow.
I know a rotator cuff injury can be cause by excessive overhead movements. I have tried stretching and icing but the pain seems to be "internal" as apposed to a surface muscle- knot type thing.
I have been climbing more frequently and harder over the last month and am disappointed with this injury as I have recently finished a spell with having physio on my right shoulder blade/back for a some strain and knotting caused by a shifted rib. If anyone has experienced something similar and can offer some tips it would be much appreciated - cant afford to go to more physio right now!
Want it to go away so I can carry on hiiiiiting it

Thanks
