Two weeks ago I feel that my left ear is blocked so went to Ent but he said that there is no infection but little swelling so he prescribed me anti allergy tabs. But still now I feel the same and also I feel little sensation in my left side head at the top and sometime at back of head He also advised me to take steam so when I take steam cough comes and I feel like cold that comes in initial stage . Now after two weeks my ear is same blocked , head sensation going on but minor not severe , sometimes feel like breathing problem and throat is also sore sometime. I am confused if it is cold so why it is not coming out from so long. Or it is some serious problem related to brain. please help.
