Hi! I am 17 years old male. I have been suffering from headache for 7 to 8 months. At the first stage it lasted for 2 to 3 mins. After that it had increased its duration. At that time it was on the right side of my head. Now it is increased too much and lasts for 4 to 7 hours. It is now concentrated on one point of my head above the right ear. Along with this I have also been facing memory problems for 2 months. I forget things too much. I even not remember what happened yesterday. I also not remember a major part of my past. Moreover I also have some little  coordination and balance problems. I also sometimes feel weakness in my body. Please tell me which disorder this is??
