GERD and Heartburn

First off, I'm 22 years old (male) and I workout regularly. I recently decided to start jogging, very light, just enough to get the heart pumping. This basically turned out to be an impossible task, from all the fluid building up in my throat.

I have to spit this fluid out on a regular basis during the day, like every 1-2 minutes. It built up so fast from jogging that I couldn't even make it to the end of the street without spitting it up. By the time I finished my little quarter mile back to the house, I just about fell to my knees, bent over and spit up a strand of fluid that was so thick and stringy I could barely cut it away from my mouth. It must of been 3-4ft in length. The grossest thing I have ever seen.

I'm currently taking meds for acid reflux, although it helps, the fluid is still a constant issue. It hurts my throat in the mornings when I wake up and my voice is really hoarse too. I've tried not eating 2hrs before bedtime, and elevating my head at night. It seems to help.

Occasionally I have these burning sensations in my back...started out in the chest awhile back. I was driving home when it suddenly became painful to breathe. Went to the er and took xrays. They said it was just inflammation in the rib cartilage. I was wondering now if the burning came from the acid reflux.

Is it typical for reflux sufferers to have trouble exercising? Also, I'd like to find out if Gerd can cause a distinct body odor in some people.
