If you are having pain without obvious cause you really need to see a doctor.
I could list here a 100 assumptions (given that I have never met you and know nothing about you)
some would be serious, some would be so minor as to not even be worth thinking about.
You need to see a professional who can assess you

I had a complete hysteretomy done on 7/2004. It will be in july a year, because of the heavy bleeding, I was recceiving injections of pro-crit and iron. Since my surgery, no problems have occur until recently. I don't know if its related, but I get some sharp pain which goes down my left leg. I take motrin which helps, but the pain or discomfort comes back. Other than that the hot flashes are not bad, which is great. I'm not taking any hormornal pills. Do you think this is part of the problem? I need to be on them. Healthwise, I am doing well. Can you help or advise?
