Leg weakness

Hi... I am a fairly normal (I like to think) 27 y/old female. I have recently (month) had continued weakness in my leg. It first began in both legs and was really bad. Now it seems to primarily be in my right leg and not near as bad. I can't find any rhyme or reason to when or if anything provokes this. At first it was quite comical because I am literally stumbling in the office holding onto the wall. But frankly, it's quite annoying now. I can't wear heels because I have a harder time catching myself. There is no pain associated with this. It's as if my knee or leg just decides it can't hold me up. Ithought  maybe had an overactive thyroid as I am always tired (but I'm a mother of 3 and wk fulltime) and can't see to gain any weight. (not that I want to but I can literally eat whatever I want with 0 worries). I finally went to the dr after I had trouble concentrating specifically while driving and almost hit a few curbs. I also have noticed tremors in both hands. This first started about 3 months ago. I was trying to hold my oldest hw paper to explain something and my hand was going CRAZY. She thought it was hilarious. It lasted 2 full days. Woke up and it was gone. Now only slight but enough for other people to notice and ask about it. SO my dr did blood work. Everything is NORMAL! Here is where I am SO confused. Originally she had said maybe I'm depressed... I really don't think I am though. While I was in her office for another sinus infection she said I was going to get a shot. Then it dawned on me. My leg symptoms started after I received a shot or right around the time. I asked if any correlation and she went and talked to another dr. They both agreed I should see a neurologist, so my appt is set for next week. In the mean time I am so anxious and worried. Any ideas? I haven't found any sort of illness with my symptoms...

  Hi make sure they look at ur blood panels for low levels of vit D, B12, magnesium and potassium.

  It can affect u more than u would think.
