Hi Hgoddard, welcome to H.C.M.Forum. you have suffered with gastric problem now you are facing weak ness. sub acute gastric irritation can cause all these symptoms, if you neglect diet controle. eat more of curd in the food, eat bland food with low spices and chillies, avoid out side foods and junk foods. consult physician and use the drugs for controle of gastric symptoms. better to take an E.C.G to exclude cardiac involvement as this also produce the same symptoms. best of health.
