Hello there. Based on only so much history the possible causes are a plenty. We need more history. Along with history, the physical examination which we do will give us additional clues as to what you might be suffering. Then we may plan for investigations if necessary. Only after going through all these steps we can come to a exact diagnosis for which treatment can be started. Consult a physician near you in person and get yourself checked out. He will need more history than you have provided here. Hope you get well soon. Regards

We need more information regarding your symptoms. It is better to see a physician get examined and treated.
