I have suffered with Asthma since I was very young (I am currently 21 years old). I have always carried a Ventolin inhaler which sometimes works (and sometimes really doesn't), but recently, my chest has become tight a lot of the time, I am short of breath quite a lot and I only really have to bend down for a while or walk up the stairs and I will be really out of breath and my chest will feel tight. The only way I can describe it, is that I can actually feel my lungs in my chest, they feel very heavy.
I often get a very dry, non-productive cough, but the chest tightness and shortness of breath are causing me the most inconvenience at the moment.
Should I go to the Doctors? Is this normal?
