i am not a doctor but from what i have read/heard many people who have suffered a concussion complain about relapses/worsening of symptoms after they drank alcohol. so if you partyed and drank alcohol, that may be the answer why you are experiencing symptoms like that. for some reason, alcohol is big no no for people who have suffered a concussion and thatīs maybe for life. because i have read many stories of people having recovered from a concussion/PCS completely and then drank a lot a couple of months later and the symptoms returned. stay away from the booze. i would say at least for a year or two years. months is nothing when it comes to brain injury/healing. after those years i bet you wonīt even want that liquoir no more
