Original injury to arm when a person pulled me from the floor by my arm and it hurt my shoulder. Time helped and it mostly healed. I then tryed to put compression stockings on a persons foot and when I pulled the stocking open to put over the foot, I got a pain in my shoulder which radiated down my arm; it hurt to straighten my arm, but did slowly. Tried again to do stockings( yes, stupid) and it hurt worse. Gave up. Now, doing various little things, sometimes triggers the pain and radiation down arm and makes it painful to move. Have to move gradually to staighten arm. Walking my Great Dane of course does not help it either. I had it xray-ed before the stocking pain inducing event and it did not show rotator cuff problems. It does not hurt all the time, just when I reach,pull,push, or other things and then it hurts; sometimes a little, sometimes alot. If I lean on my elbow and support my chin, when I move then the shoulder/arm pain hurts. It is a habit when reading email and I remember and then it hurts when I move from leaning. All of this pain has happened just since I tried to hold open the compression stockings with each hand pulling them open and holding it open. Does it sound like I could have torn something at that point? All my GP says is: Ice it. I am on medicare and Drs. and Mri. cost me so much more expense, so I am wondering if this sounds like a tear that I should have addressed or just a bicep tendinitis? I am really needing to know what I should do. I have osteoporosis, but not osteoarthritis that I am aware of.Thank you in advance for all and any help.
