Hi I'm 16 and have had really weird symptoms lately!! I have Epstein Barr virus but something else feels wrong!! I have tightness in chest mostly at night, gas problems, swollen throat around the base of my neck and I have had a feeling that something is stuck in my throat! Could I be having esophageal spasms? Oh I also have spinal muscular atrophy which could have a role in this!! Please help, I need answers and I'm really worried!! Thank you!
