bluebelle,
I just finished trigger point injections last Tuesday. I get them in my neck, shoulders & upper back. The one's I get are a series of 3 (1x week for 3 wks) and have them approximately twice per year. If I could, I'd get them every week because of the relief that I get. But, one of the medicine's is a steroid and they are harmful to body organs if used too often so Dr. says he'll only do twice a year.
The down side, it's a needle -
and relief only lasts 4-6 weeks.
