I was sitting on my couch and had my head bent over, in my hands,
My friend came up and punched the back of my neck and it swelled and burned and stung...the next day the swelling went down but I still have something protruding...its kinda a hard bulging bump
My muscles down my back hurt off and on and I will get sharp pain going all thro back at times
Can someone please tell me what it is and what to do
