question: I had what I believe was an excersize induced asthma attack after swimming a few laps and after 2 uses of my inhaler was able to breathe more normally. I sat for a while and then my husband drove me home, I was very shaky and had some blurred vision. I took a hot shower and rested on the couch and felt much better. I went to change for dinner and discovered quite bright veins all over my torso. My left shoulder is tender but I attribute that to the backstroke I was accomplishing. While I still feel a bit weak and not 100% I am much better except for the veins. What could this be? I am tan and not too pale. I have allergy induced asthma. Thank you
