Fibromyalgia Symptoms HOME

I'm experiencing all the symptoms of Fibro and I've been dealing with IBS, Depression and headaches for years. But after all my research online, it seems like if I go to my doctor and ask him to help me find out if this is my problem, I'm going to be going through a lot of testing. My research has also shown me that there doesn't really seem to be much specific help available. I'm sorry if this seems so negative but I have to wonder, what is the point of going through all the (possibly painful) testing? I'm very confused and seeking advice. If I get the diagnosis, will it really make a postiive difference in my life and with my symptoms? Please inform me, Kat
