New Symptom-Burning in hands?

I have been getting burning sensations in my thumb tips for a week or so now. I have a feeling it's carpal tunnel or ulnar tunnel, but the doctor told me it's all fibro. Now I'm getting it in my middle finger too all along it and not just the tip. I'm still not convinced this is all fibro and was hoping some of you could tell me if you have ever gotten this? Thanks, it has me worried really bad.

I get a lot of aching in my hands as well, more so when it rains it seems. I've had a lot of blood tests done I'm not really sure what they were for. I know I got tested for arthritis 3 times and they all came back normal,but my dr. thinks it may be that too now so he's sending me for xrays. I have carpal tunnel,but was always told it was very mild as well tho I haven't had it tested in a while my neurologist did look at it about five or six months ago and didn't seem worried. Sometimes my hands and feet will hurt the same way together,but hand and elbow pain seems to be what's troubling me most lately.
