I am a 32 year old male and I am currently having the medical year from hell. These last few months have been stressful on me and I have never felt this stressed in my life. I have recently been getting massage and chiro to combat the stress. I had bloodwork done about 1 month ago and everything came back fine. However this past week I was driving home and all of a sudden felt as if the lights were going to go out. This lasted for a few minutes and then went away. I was driving the next day and walking at my son's school, during this time I felt like crap and like i was going to pass out. I went home and immediately felt better. I have been fine for the past few days and then it happened again today. brief 2-3 mins of feeling like I am going to pass out and then I am fine. I have also had horrible gas during this time, and burp almost non-stop it seems at times and then at other times I have no gas. I am scared and it just seems like another roadblock has popped up as I have been trying to get better. I also had my annual cardio work-up earlier this year, good results again. Any input into what might be going on is appreciated.
