Tammy - I'm sorry that the injections hurt so much, but hopefully you'll feel the relief in a couple of days. I have had nerve blocks, nerve blocks and trigger points, and just trigger points (on different occassions). After several of them I have felt ill by the next day. I think that can be a side effect of the lidocaine or whatever they use in them. That being said, 2 days afterwards, I feel better, and pain levels are down. The way I figure it, I can deal with a headache or the "funky" stomach feeling for a month or 6 wks of relief. I just had 6 trigger point injections this morning, and *knock on wood* so far, so good. But, I do agree that the doc needs to know about your reaction both for future treatment and in case its an allergy.
