Since last few days in morning I have muffled ears. I feel something wrong with my ears. I feel blockage of sound. But if I press both the ears and its okay for sometime. But I have my lunch it becomes normal. And I feel better. I feel that the brain has stopped working. And this leads to negative thoughts. But after lunch everything seems to be okay. Last night I had a pain in the right forearm for 2 hours and then it stopped. What could be wrong? I am really worried.
