Ive been having severe pain on the right side of my head primarily the right temple, and its dibilitating. Ive missed school, work, and cant even sleep because the pain hurts so bad. The pain started on a friday and still remains the only reason i am functioning now is because im on medication but when it wears off the pain comes back and worse than before. What could this be? my doctor ruled out migraines because its lasted such a long time and i dont have certain symptoms that would pertain to a migraine. Im supposed to go and get an MRI soon, but wondering what this could be, they said muscle tension headache but for it to be going on this long he said that it is kind of unlikely too. someone help!?
