ibromyalgia
"I was prescribed gabapentin for pain due to fibromyalgia. I was in severe pain. My pain doctor told me she thought I should try gabapentin for relief for the fibromyalgia. It actually worked very well. The problem was that before I started taking it I had no problems with breathing or water weight gain. After only a month of being on that medication I had to go to my normal pcp because I felt like I couldn't breathe. I could feel water all the way up my thighs and into my belly. I had gained 30 pounds in one month due to water weight. I ended up being diagnosed with pulmonary hypertension because, I believe, of gabapentin. I will never use it again. I'm still on oxygen 5 years later."
