Ear Acupuncture question please?

Hi I am just wondering if anyone here thinks that it is possible that acupuncture could possible make things worse? I have had ear acupuncture, four times now over the course of the last month. I have had this for digestive problems and endometriosis, have a lot of inflamation and this week the pain seems to hve gotten a lot worse. Also tonight when the pins went in one of them hurt sooo much...I know that sometimes there is an healing crisis but should this not be short lived. I have had ear acupuncture before and I did feel that it worked a bit, I definitely feel relaxed whilst I having it and after for a while.

Thanks...Moonie
