Hey people! About a week and half ago, I was doing dips and i when doing calisthenic exercises im pushing for failure so the intensity was high. well, i was pushing upward on my last rep I had this huge throbbing pain in the back of my neck pounding with my heartbeat. It looked like i had a rash on the back of my head for a few days afterwards and cant figure out whats wrong because, while the rash is gone, the pain and throb with high intensity persists even causing some nasty headaches on the back of my head. Pehaps i blew some blood vessels? Herniated a disk in my neck? I dont know what it is and if anybody has any ideas, it would sure help alot. I wrote the whole sequence of events as a way, perhaps, to come up with something wrong. Thanks.
