i have a pain in my neck and shoulder on the right side of my body. Pain comes and goes very often one minute its sharp and severe. next its just mild and sore. I have shortness of breath. when I exhale I wheeze, I can hear my heartbeat in my wheezing. I get out of breath and breath real heavy doing simple things such as walking. When i bend over for a few seconds and stand up i get lightheaded and feel like im about to faint.
