I am 2 months post concussion and i have had constant head pressure since the accident. The crazy part is that I just had an MRI last week and since then I have been experiencing horrible throbbing headaches in addition to the pressure. Has anyone else experienced this?

I am also being stepped down from Nortriptyline and Amantadine so I'm not sure which could be the trigger. I do not tolerate medicine very well, but these headaches are not responding to Extra strength tylenol. Anyone else who is sensitive to medicines....what has worked for you?
