I've been getting a mild yet stinging type pain in the right side of the top part of my head that randomly comes and goes. When the pain strikes it only lasts 10-20 seconds and then it fades. I'd say it happends about 3-4 times a day and I havent had any injuries in the area. This has been going on for about 2 months now and I've been debating if I should go back to the hospital to get it checked out. I went about a month ago for another issue and mentioned the pain. They checked my eyes and told me since I didnt have a Fever with it, it probably wasnt serious. I was expecting a scan but they didnt think it needed to be done. I've also been Feeling a bit dizzy. It Feels like I'm really tired all the time, but I don't notice it when I'm busy. I'm a pack a day smoker and while holding a cigarette I noticed that my hands are shaking, but that may be from the nicotine. Please tell me what you think may be causing these symptoms.
