Shoulder Osteoarthritis

I'm an auto detailer. I only use my left arm/hand because my right is handicapped. After a day of work, i used to have sharp pain in my shoulder area. It got so bad that i had an MRI because it was affecting my sleep. Sitting & sleeping made the pain worse. Turns out it was "extreme arthritis," per the radiologist's report. Around the time I got the MRI, I started taking BCP 157. My doctor referred me to a surgeon who referred me to a physical therapist. In the meantime I'd been taking BCP 157. About 10 days after the surgeon consult, I went out of town for a week. When I got back, I had several jobs. Between the MRI & getting back home from out of town, about a month had passed. A month of me taking BCP 157. The pain was greatly diminished at that time. I've been taking it about 2 months now & no pain. The only thing that changed between having extreme pain & now is I've been taking BCP 157. Did my arthritis magically go away? I seriously doubt it. It has to be the BCP 157
