I am a 20 year old male who was prescribed 200mg of doxycycline
twice a day to treat confluent and
reticulated papillomatosis, and
after 3 days, I started developing <span style = 'background-color: #dae8f4'>headache</span>s
. I stopped taking it after a week, but my headache
persisted. I feel a constant pressure in the back and top of my head and my neck that is not throbbing but more like something pressing continually.
