From the past few days i am facing heaviness in right lower abdomen with light heaviness in right chest, feeling of something stuck at the right throat and belching feeling. This kind of heaviness is more seen after pasing stool and sometime after having breakfast and lunch. But it gets better after burping, but then again heaviness comes after a few minutes. The heaviness is felt while i sit. I also feel that my bowel is not clear properly. Sometime stool is loose and sometime hard. But no any pain in either in stomach or abdomen. Appetite is good.But this issues hampers during my daily routine which makes me more upset and sometime i have panic attacks also. Sometime after the issue faced, my right nose gets blocked and i feel like having breathing issue to. Please tell me whether the issues i am facing is a serious condition or some other stomach/abdomen problems.
