I can totally relate to the "head pounding and pressure"!! I'm 29 now and 4 years ago I started to experience a pounding in my head, not really a head ache but more pressure and it would get worse if I bent over or moved too fast. I also experienced a "tight" feeling in my neck! I didn't really pay it any attention bc I suffer from horrible sinus problems so I just assumed it was "another sinus infection"! I was VERY healthy and done fitness training 4 times a week. 5'7 and 127 lbs! I started to question why I just felt like crap every single day! I worked out, ate right, didn't drink, smoke etc?! Well one morning I woke up and my face was a little swollen, along with my neck and my cheek bones were sore to the touch! I called and made an appt with my dr (months from the 1st time I had exp the pounding) and she assured me it was just another really bad sinus infection. Took my meds and nothing changed! I didn't wanna be one of those paranoid pts so I just let it go and tried to deal with it. 2 weeks later I was watching tv and my right eye went totally fuzzy...it started throbbing! I took some Tylenol and laid down the next morning went and seen my dr again. This time she gave me a shot of Rocephin (excuse spelling) which is a very strong antibiotic. That helped for a few days but on a Sunday morning I woke up and put my feet on the floor and instantly knew somethiNg was wrong! My legs were swollen 3 times there normal size and I could feel the pressure in my face and head, I was at such a loss as to what was going on I called my fitness trainer to see if I had been "over doing it" exercising?! He assured me that wasn't the case and I needed to seek medical attention ASAP! I went to the ER am they immediately admitted me and started to run test. I stayed in the hospital 2 weeks to find out I had LYME disease!! I'm not replying that everyone with pounding head or swollen anything has this but it is over looked VERY easy!! It's very serious if not treated and can cause long term damage! I feel 100% better than I ever have and I'm not blaming my dr one bit for not knowing bc who goes to the dr and says, "Hey I think I have LyME disease!" it's a simple test it only requires blood work and that's it!! Mine was treated with a 60 day antibiotic taken once daily. I was also given pain meds which I didnt find necessary to take BUT LYME disease can cause serious pain! I can't even tell you where I came in contact with the bug so don't think you have to have the "tick" on you bc you don't!! Like I said, I'm not saying my symptoms are the same for everyone but I can tell you they drove me crazy! I seriously thought I was losing my mind lol. Pounding head pressure, heart palpitations, edema, feeling so fatigued, weight loss, aches and pains and tightness. I never would've thought in a million years I would ever get LYME disease but I guess you can!
