I've been having a shoulder problem ever since last summer. The day after a bench press session I developed pain in my right shoulder. It slowly faded but I could not and still cannot do horizontal pressing movements without pain(all other movement patterns are fine). I had never had any pain in my shoulders before this and it didn't hurt while working out on or before said day.
I went to the doctor within a few weeks of little to no improvement and he took some x-rays and found nothing. He told me to rest up and come back in a month or two if pain persisted. Well, recently I went back and had an MRI and the only thing they found was tendonosis(which I'd never heard of). He prescribed me 2 weeks of anti-inflammatories and told me that should do it.
Upon further research, everything I read tells me that tendonosis is worse than tendonitis and that anti-inflammatories will do me little good and that the best thing to do is eccentric exercises for the injured body part. If there is anyone out there who is relatively knowledgable about such things I would much appreciate their input. Thanks for your time.
