I also had a torn rotator cuff in the right shoulder requiring two anchors earlier this year.. Prior to having surgery I experienced sharp pain in the forearm of the same arm but was told I might have a slight case of tennis elbow. After the surgery for the rotator cuff the forearm did not hurt any longer. The doctor did tell me at that time that there are nerves that run from the upper arm down into the forearm but he seemed to think the tear and pain in forearm were unrelated.
I had taking Cipro a week ago for 30 days and now my should and rotator cuff hurts. Expecting worse soon. Any idea please.
