Girl, this is scary! But get over your fears and GO TO THE DOCTOR!!! IMMEDIATELY. Just imagine how much more scared you'll be if this continues and you don't know what it is. Besides, you may be putting yourself and your children at risk.
Odds are, there is a treatable cause for your tremors. But you'll kick yourself if you wait and later find out that you've allowed a small problem to become major by letting your fear paralyze you.
I recently had some weird rhythms with my heart. Heart disease runs in my family, so despite the fact that I maintain a high fiber, low-cholesterol diet, exercise regularly, and am well within the recommended weight boundaries for my height, I was TERRIFIED! I went to the doctor anyway and within a week was assured by a cardiologist that the problem was nothing. I share this with you only to assure you that I can relate to your fear. But look at your kids and tell yourself that you're doing it for them. SUCK IT UP AND MAKE THE CALL TODAY!!!
Good luck!
