Since the end of november, I have been continously having problems like Headaches, cold, fever (rarely), stomach upsets, indigestion, flatulence etc. I consulted a doctor three december and was given antibiotics and medication for gastric problems. It did help with the fever, but my headaches, indigestion, flatulence problems continued. since 2 weeks I have been having a bloated feeling, indigestion, recurrent blocked nose(I take ortivin spray for it) and excessive flatulence. I have been frequently feeling brethless and tired. What could be the reason and what can I do for it?
