I would suggest having a total blood panel done. Could be B-12, thryroid, iron etc. You need a "Complete Metabolic Profile". That covers just about everything. Now go have that done. I think you have wasted enough time. Now go!

I agree with CarolDiane. I thought B-12 as soon as I read the title.

Either that or hyperthyroid Keli. Symptoms mimic either. But, like you, I am almost willing to bet B-12 defishency,

Well the first thing you need to do is go and see your doctor

He should do a full blood screening which will pick up the most common possible causes, then go from there.

Unfortunately there's 101 conditions that can be responsible for these symptoms. So get yourself down to your doctor
