On Monday at about 2:30am I got frustrated and hit my head (front, forehead area) with my hand about 3 times pretty hard. Afterwards I noticed some head pain, I went to sleep and then woke up at about 3pm with the same head pain and freaked out (I'm an extreme hypochondriac so I freak out very easily) so I went to the ER, they ended up giving me a CT scan which indicated that everything was fine. The doctor told me to come back if I notice worsening head pain or dizziness. Today when I woke up my head was hurting more (in the back of my head) I also felt dizzy, light headed, sensitivity to light, rining in ears, and so on so I went back to the ER, they looked over my CT scan from Monday and said I should be fine. Since then my head pain is still here and I've also been feeling a pain in the back of my head and the area feels warm and then cold sometimes, I don't know if that is normal with a concussion. I also don't know if this is my anxiety causing some of these weird symptoms, because my anxiety has been a HUGE issue the past few days and my anxiety has caused strange symptoms in the past. Should I be worried?
