Hey! I am a 21 yr old physical therapist assistant student. My grandmother actually had MS for over 30 years and passed away in 1999 from pneumonia. I am not jumping to the conclusion I have MS, but it does worry me that there are some genetic links. I know something is not right with me and I have yet to figure it out. My hands, lower legs, and feet go numb and tingle quite frequently. I also have a pretty bad eye twitch that comes and goes it will twitch a lot for a few months and then goes away for a few months. If I sit for long when I stand I completely loose all my vision, get very dizzy, and lightheaded it feels like i'm fainting but I never actually faint this also happens when I get hot...its really bad in the shower or in the summer... I can not swin in indoor pools cause I can not breathe in there it makes me wheeze very bad but that has happened since I was about 12 in hot steamy places. I also have noticed I get sore a lot now and stay pretty tired and have lost a lot of balance. I was a cheerleader my whole life and even in college, and these symptoms seem minor but when you go from perfect health to feeling these things it has really started to freak me out... I know joint pain is not associated with MS but my knees also have started aching really bad its worse in the mornings but I think that is from a life time of overuse. I have never had any kind of health problems or anything. I just need advice am I freaking out or does something seem wrong? help please!
