Hi, I had a stomach bug a few days ago and took medication for it, ate good fibre foods and saw it through. It seems to be gone now now but I still get a slight burning sensation and today I felt a few pokes on either side of my belly also closer to my lower belly on the right hand side. It did not last long and eating did help but I m worried about gallstones or appendicitis. Is this a concern or am I being paranoid? My biggest problem in recent months is heart burn which may be caused from a post nasal drip issue, could this have a contributing factor? All of these problems started when I had gastric flu a year ago, i feel as if it was never fully out of my system. What do I do for normality again? Please help, it s really frustrating to live with a constant irritation of watching every thing I eat and wondering if it will affect me tomorrow.
