Had a steroid injection into my shoulder. The doctor mixed an anesthetic with it as I recall. It provided a lot of relief. Eventually, 6 months later, I had to have rotator cuff repair and that was dreadful but cured the problem beautifully. Sometimes we have to try what the doctor is suggesting since he's the one who studied medicine for 8+ years or more, correct? What I tell myself: No pain, no gain, Baby.
