It all started when I was on Doxycycline for 10 moths and clindamycin solution for over a year. I ended up having this noise like air was coming out of my chest when I would twist my torso. I ignored it. A month or so later I noticed I was getting out of breath when I would do something like vacuum my car out or carry anything slightly heavy. I then noticed slowly I was getting tired. I was having trouble sleeping. I went to doc he said I was exhausted and gave me ambien to sleep. I took it but no better. I went to another doc who then gave me naproxen (?) for some shoulder pain. My pee turn brown and I had these severe stomach cramps. I stopped it and my stomach started aching after that. Now I can't eat without feeling full really quick. I do have an upset stomach most time. I had little diarrhea now I am constipated and on meds for it. I know the antibiotics messed me up. I am seeing a gi doc who thinks nothing is wrong. I have been complaining that my heartbeat was in the 70"s till I got sick now it is 90 something or a little over 100. My family doc thinks it is anxiety and my gi doc said I need to see family doc to check my heart out. I do remember this day when I was really out of it. I remember walking up these stairs and my legs got heavier and heavier then I was getting out out breath. I was not dizzy. I was really tired and out of breath. It took me about 3-5 minutes to get my breath under control. The other day I had to run out to my truck and I was in a hurry so I walked fast and had a handful to carry in. I got really out of breath by it. I don't feel this is just anxiety but I don't wanna go to doc and have them run test that waste money. So does this sound like anything like heart trouble or anxiety? I also have lost weight not trying. I am becoming very lazy because I am tired all the time. I do feel shaky sometimes.
