I have pain in my left side of head-skull since 3 months. Sometimes, a specific area hurts, and sometimes the whole left part. Also, some days back, i felt a swelling on a spot on the left side only. I also feel intense pressure all the time in my left side of head. And today, my left side of the face was fweling numb and irritated and a bit swelled near the lips. I am also having vision problem in my left eye, but it is since many days, (I already wear minus 3 spectacles in both eyes) I am also having reading difficulties.
