I am a 33 year old 250 lb healthy male. I take 20 mg Nexium for GERD daily and 10 mg lisinipril for pre-hypertension. I was taking 1db overdrive (supplement) for about 3 weeks until I ran out a week ago. I run 3 miles a day every other day and bike 8 every other day and do some toning and strength training in between. I have never had a problem with headaches unless I'm very ill from the flu or a doozy of a cold.
Only recently for some reason, I get car sick when my wife drives and she drives better than me and I get a little dizzy/nauseated from looking at my computer monitors for too long. I have never suffered from either of these before. Second, I get a very brief, sharp but not un-bearable headache from a pinpointed location at the center of my brain (this is what it feels like). Additionally, very recently I have started to sweat excessively in my armpits without exertion and my whole body sweats at night. I also have some very lower back pain (very minor but noticeable). I have lost about 15 lbs in the last month so the sweating has gone down considerably but the other symptoms remain. Am I just getting old or could there be something more seriously wrong with me?
