and bordering on freaking out...

I was given a 10 day, twice a day prescription for Doxycycline. I was supposed to take my 4th dose an hour ago, but for the past 12 hours or more, i've been experiencing a mild disturbance in my sense of balance, and more lately, a sense of pressure in the back of my head....not pain...but just a strange sensation of pressure, as well as a sensation of tension in the back of my neck.

I experienced the pressure and heavy-headed feeling quite often several months back, but it went away on it's own....this time im worried it might be increased intracranial pressure as a reaction to the Doxy...but i haven't really had any headache or blurry vision. Any ideas?

Doxycycline make me feel like death, nauseus, dizzy, headachey, flu like.

Its from the effects of the Doxycycline but see your doctor about it if its causing you to have problems.
