I hate to read you are in pain and suffering because you do not have insurance. Have you tried topical treatments like biofreeze or stopain? Does heat provide any relief? See if there are places near you that offer free or reduced cost care. You might also contact the therapist and see if they will work out a plan for you or a reduced rate. These times are tough and many of us are suffering, including those people whose services we can no longer afford! The worst thing that could happen is they will say no. The best would be a plan or a referral to someone who will work with you.
Please let us know what happens and, if there is something we can do for you, we certainly will.
I had extreme pain and after MRI they found that my joint fluid was leaking and causing cyst due to extreme shoulder instabilities. Had total reconstruction. Wouldn't recommend it but doesn't hurt as bad, just was bad on me b/c I have Fibromyalgia. Look further, they will find something. Laproscopy surgery for rotator cuff is a lot easier than letting it get worse and more painful surgeries.
Have you ever had an MRI, or even x-rays on your shoulder? It could be a rotator cuff problem or something torn. I don't think the doctors can tell unless they get some kind of films and that's probably why they're just saying arthritis.
Is this the only place you have pain?
