Hi, I'm a 28 male & do regular exercise; so consider myself fit & healthy. I'm sure my problem below is common (& hopefully not even a problem) but thought I'd check anyway!
I regularly cycle, run & do martial arts. Sometimes, when doing heavy exercise, I feel dizzy, ill & get bad shakes especially in my hands (a bit like really bad pins & needles). I also feel very weak &, strangely, my ears block up. It a horrid feeling that lasts for about 15 - 20mins before I feel fine again to carry on.
I saw a doctor about 3 years ago & he told me to eat more sugar based foods before exercise. But this doesn't always seem to help.
I do eat before workouts & drink a lot of water. I believe my breathing to be controlled when exercising & I do plenty of stretching too.
Am I just pushing myself too hard? Perhaps my diet is poor (I'm wondering whether I'm not eating enough as I'm slim).
Many thanks,
Mateus
