Kenalog Kenalog Injections, Aching Muscles, Trigger Points, Muscle Spasms, Chills

I had Kenalog injections a few days ago for MyoFacial Pain Syndrome. They are used for Trigger Points in the body that cause severe muscle spasms.
I have experienced these spasms for about three years. The first three times I had the injections I had no side effects. But the relief from the pain only lasted about three weeks.
So the nurse practitioner upped the dosage the other day. Since that evening I have been suffering from chills, sweating, fatigue, lost appetite, anxiety, aching muscles, and insomnia. I wake in the night several times sweating.
The pain in my upper back has subsided now but am not sure it was worth it.
I called their office but have not heard back from them.
Am so tired from suffering already and I hope the side effects subside very soon!
