Ok I've had problems for about 3 weeks and I'm just uncomfortable and miserable!! My throat has been swollen in the front of my neck and feels like something is stuck or moving and it's kind of hard!! I haven't slept too well and I could have anxiety because I tend to worry a lot but my lungs feel like they aren't inflating enough! I feel like I can't get a good breath! I've coughed up mucuos, have had chest tightness, and in the middle of the night I feel like a wake up gasping for air and my heart almost feels like it stops for a short period of time which is really scary!! I've been very tired also!! I just want to make clear I have spinal muscular atrophy and had a rod put in my back a couple of years ago due to scoliosis!! I really would love some answers and appreciate any help I can get!!
