I suffer from chronic fatigue syndrome and fibromyalgia. I have problems with painful joints and have fluid on my knees. I tried Aqua Ban to try to relieve the fluid on my knees. I started by taking 2 tablets x 2 times on the first day, I was fine. The next day I took same dosage. In the afternoon I started feeling unwell. I went to bed as I had terrible tummy pains, felt sick and went downhill quite quickly. The next day I felt worse and had cramping pains all day. I stayed in bed with a hot water bottle. I had no energy at all. This went on for 4 days and eventually I ended up with a pain in my pelvic region. I can only think that the Aqua Ban had such an affect because of the chronic fatigue/fibromyalgia? Has anyone else had an experience like this?
