one word...
DOCTOR
I was feeling pretty bad a few weeks ago, started getting really weak and feeling my hands shaking a lot...
Went to the doc, got the problem quite possibly worked out and now working on the solution

Got me some meds to alleviate the symptoms, and will soon be working on the actual problem...
I HATE doctors!! (no offense Doc, you're ok

lol )
But I broke down and did it and SOOO glad I did!!!
Having the shakes really sucks :/ lol
AS mentioned above, you're just gonna have to break down and see a doc... it could just be the flu but many times you're better off knowing for sure

Lessens your stress a bit knowing as well
