I have been having sharp pains in my head, mostly in the back left side. I also get them on the right side and the front temple areas occasionally but mostly on the left back side. I get them every so often and they last a few seconds each time they strike. The length of them varies. I have been reading about this and it appears alot of people get them too. Not sure what they are (ice pick headaches??) or what causes them. The weird thing is, the research I've done on it says most people that get these sharp pains suffer from migranes. I do not nor have I ever suffered from migranes and I hardly ever get headaches...so I am not sure why I'm getting them. I haven't been to the doctor because I'm not a big fan of doctors these days...they tend to misdiagnose and cost you a lot of money in the long run. Anyway, I would like to know what causes them...can't seem to find anything on that...so if anyone can help,that would be great as I would like to do treatment that doesn't involve medicine. Another weird thing is, when I drink red wine, I instantly get them. The first drink of wine I take causes them to strike. I found this very strange but I have noticed this right when I have a glass of wine...could they be caused by alcohol or the sulfites in the wine and/or caffeine? Can anyone give any insight? Thanks
