I think the head stuff is related to benzo withdrawal - I've had the head pressure all over, first in my temples, then forehead, then at times in my jaw and ears. Lots of sinus pressure, swelling, etc. I recently had a CT scan and an MRI and they came back negative. Probably the benzos causing your pain, but for peace of mind if it continues, go see a doc. I rarely have the head pain anymore (but have numerous other symptoms). Ears and jaw still gives me trouble.
