I'm 18 years old and I've been having vague symptoms for years. My primary care doctor is very hands-off in her approach. (Example: I went in there and explained how fatigued I was feeling. Most doctors would educate patients on normal sleep requirements, but also test for common conditions like anemia. My doctor said go to bed earlier, no tests).
During the past week or two, I've been having more severe symptoms. I wear contacts/glasses but my vision seems to have gotten suddenly worse. I know this could be normal, but it's becoming a bit of an issue when I drive at night. I've been having sudden, severe headaches that cause debilitating pain, but quickly go away. Longer lasting, less severe headaches have also become more common. While I've never had a particularly good memory, I suddenly can't remember anything. Sometimes, I can't even finish a sentence because I completely lose my train of thought.
I do not know if this is related, but I've had an ongoing problem with my heart rate between sitting and standing. My pulse rate will jump from 80bpm to 120bpm, and the increase lasts at least 2 minutes after initially standing. This causes me to feel lightheaded and dizzy, my vision will also often be affected. (A white flash that momentarily obstructs my vision). Although I don't exercise like I used to, I am at a normal weight and I'm young. I don't understand why I'm having this problem.
I need to see my doctor about this, but I know she will tell me to take some tylenol and be more careful when I stand up. I would like a more proactive approach, so I need to know what tests I should ask for.
Does anyone have any ideas concerning these symptoms?
What tests should I request?
