I am 19 years old. 3 months ago I got a bad flu which left me feeling tired and brain foggy today. The temperature may rise to 37.4. I was told that maybe my body is fighting the herpes virus. Then I took tests, everything was normal except for lymphocytes of 63% and low granulocytes. Now I had an MRI of the brain (they found cysts on both sides), a test for thyroid hormones, and fluorography for diabetes mellitus. Everything was clean, I re-tested the usual blood test and everything is also normal except for lymphocytes 47%, the symptoms persist. Today my throat started to hurt and my voice was changing. The day before yesterday I sang a lot and smoked electronic cigarettes, I smoked and before that I drank very hot teas, and yesterday I also smoked an electronic cigarette. Today these throat symptoms started without smoking. What happened with me. Can I have throat cancer at 19? And what's wrong with me anyway?
