I had caught herpes zooster viral plus trigeminal neuralgia plus anxiety 3 months ago. After recovering from that, my digestive system has become very poor and i get severe acidity ( can even smell and taste acid), intense bloating on eating majority of food items. If i eat light food i feel weak and my bp gets low. If i eat normal food, then i get acidity, bloating and my stool has most of the complex and heavy things i have eaten that day. Plus i feel like going to toilet multiple times a day.What should I do?
