Hi, I am male 25yrs old. My body feels like it has been slowly failing over the past year ever since I injured my neck in a diving accident. Since then, my symptoms have gone from hardly noticeable (besides the neck pain of course) to unbearable and constant. Post nasal drip, irritable bowels (constipation, diarrhea, narrow stools, trips to the bathroom 3-6times daily sometimes more) I also feel like my food or parts of it are getting caught in the top of my esophagus above my thyroid area. Severe neck and upper shoulder pain, as well as chest pains below and to the left of my heart. I don t know if it matters but prior to the injury perhaps congenitally I tend to have an irregular heart beat (skipping a beat) and muscle spasms horizontally accross my chest into my left armpit and upper bicep . Lastly I have very poor circulation too my legs, as well as a blueish bulging veins in my calves. I dont know whats relevant and what is not but i am terrified that my body is shutting down
