Hey everyone. I am a 20 year old male. Im 6 foot 4 and 220 pounds. For the past few months Ive been feeling nothing like my old self. I used to be an energetic go getter that was always on my feet. Around Mid December 06 I started feeling ill. One night I got extremeley light headed and almost passed out with extreme nausea. This happened on and off for another two weeks and it finally went away. I would feel dizzy, fatigued, tired, and confused alot, and had a hard time remembering things. I started to feel better as time went on, but now my symptoms are back. I can sleep a good solid 8 hours, and still feel like I have no energy in my body at all what so ever. Im not dizzy anymore, but still have a hard time remembering small things. (Like where my phone is, what I did with my car keys etc, things that I used to never have to sit and think about where I put). I get this tingling feeling in my hand every so often, and Ill occaisonally see specks of light in my vision. The right side of my neck is stiff and sore to move most of the time. I went to the doctors to get tested for diabetes since it runs in my family, but the tests came up negative. The doctors said I checked out fine, but I know something isnt right. Im not the same person that I used to be. I have no idea wht this could be. Ive spent hours on here trying to come up with what sounds like a reasonable explination for these symtpoms, but Ive had no luck. Maybe Im just over reacting?? If anyone can help me or reccomend what this can be, Id greatly appreiciate it.
