Hi, I had a car accident 9 months ago and have had pain in my neck, shoulder and back since. I saw a orthopedic surgeon today who said I have a hiatus lump on the back of my neck among other injuries. I have absolutely no idea what a hiatus lump is so would be grateful for any information. I am 36, 5ft 1 and weigh 7 st 11 lbs. I have a condition called Erythromelalgia which affects my legs and feet. Thanks
