Just been for a run in the park. I dont normally run, but i felt like i wanted to 'wake myself up'- so i did, going quite fast at first. after 10 minutes i felt like i was on fire- i could taste blood, my ears burned and i felt really sick, like my chest was ripping. Is this normal?? im not overweight, have a BMI of about 24 and i regularly horseride. Help!
