Sonic 1, I am so sorry for your pain and discomfort. I also felt severe pain in both shoulder and after going to multiple doctors I went to a chiropractor who said I have adhesive capsulitis ( frozen shoulder ). The doctor has to either dig into the affected area with his thumbs or put an interferential unit on it. So far the chiropractor is helping a little. Putting on my bra and taking a shower along with trying to sleep at night is the worse. I also went to an orthopedic doctor who gave me cortisone injections in both shoulders. I am currently in a great deal of pain because of the injections. Hope you have better luck.
In most cases, bursitis of the shoulder is caused by performing repetitive movements for an extended period of time, such as throwing a baseball, playing tennis, painting, scrubbing, gardening, carpentry, etc. Shoulder bursitis can also be exacerbated by a physical trauma or previous injury to the joint area. Your risk for developing bursitis increases with age as joint components, including the bursa, tend to decline as you get older. People over the age of 40 are at the highest risk for developing bursitis. Shoulder bursitis can also be brought on by other joint conditions such as rheumatoid arthritis, psoriatic arthritis, gout, and thyroid disorder.
