Doxycycline Hyclate and acts

took over a month for mild acne until i started getting headaches and cloudiness in my head ( i felt out there) the headache i would get was this pain in the left side above my ear.. so i stopped taking the doxy-whatever.. for a few wks now i still have this pain, especially when i touched the spot, it just feels really tender. i had a headache yesterday, it felt like it was my sinuses.. well stupid me decided to try the medicine out again today and a few hrs later what happens?.. i started to feel light-headed.. i called the doctor he told me to stop using it and i am seeing him on tues.. he also told me that the medicine shouldnt be giving these side effects.. so to tell you the truth everyone acts differently to medicines..
i am soo done with this medicine!! especially after reading everyone's comments.. im going to look into accutane which i heard works really well. hopefully i wont have any more problems!
