Has my asthma come back- what’s wrong with me?

Patient: Did my asthma come back?I am 14 years old and was diagnosed with asthma about 7 years ago. It went away very quickly, however.For the past few months, I, a usually very healthy athletic girl, have been feeling very nauseous immediately after exercise ( biking, running, etc).Sometimes I need to almost gasp for air and it feels as if my lungs are just not taking enough in.I’m not sure if this is relayed, but sometimes if I put Pressure on my thumb, for instance thumb against my pointer finger, my thumb twitches uncontrollably ( it stops).Please help me. If you would like any more info, just ask.Thanks!
