My limbs have been going numb....I think my sugar level might be off too, I think I can tell when its too high

I don’t know why this has been happening...I started working out about 3 months ago, and when I am on the elliptical thing my feet go numb after 10 minuets! I stay on as long as I can (about 15 min), but it sucks! I want to work out, and when I finally get my lazy to the gym my feet go numb! Its not my shoes, changed them...not the socks, tried all different kinds. Also I am noticing that my arms, and hands are going numb fast, like if they sit in one position for over like 30 sec. their out. It happens at work all the time, I have to keep moving. And if that was not enough, I am getting dizzy. I will just be sitting here, and realize that my arm or leg is numb, and then my eyes go, and my head spins. It sort of feels like I go cross-eyed for a second. Weird hu? So does anyone have any ideas what this might be, or what I can do for it? I don’t have health ins. Plz don’t tell me to go to the dr. Also, I am pretty healthy, and I drink loads of water :o\ ... Any ideas??
