I had bursitis in my left shoulder 13 yrs ago, finally got in to see ortho in 3 months, he withdrew fluid from the sac and it felt better, 2 yrs later got bursitis in right shoulder. The pcp gave me a shot of cortisone, days later I got Shingles. Between those few days I lost my insurance. I was in terrible pain, burning & itching. They didn't know what brought it on. I read awhile later that steroids can bring on Shingles. I was told you only get Shingles 1x, I have had them more than a dozen times.
The steroids can also destroy your bones. Most drs. don't admit to that, but it is true. I have been going to ortho for my shoulders, knees, hands, & back. He wants to give me steroids so badly, and I refuse. I told him my reasons and he smiles. He even said to me I can't guantee you wouldn't get Shingles again, but you know how the pain is, You could deal w/ it. What kind of stupid logic is that? I am not having the steroids again. My DM also got Shingles after a steroid shot, and hers came back several times, also I have had the 'lube' shots in my knees to hopefully build up the cartilage, so far, nothing.
You have to make the decision, but this is my view on those shots. I wish you good luck.
God bless. Alice.
