I am nineteen years old and am an asthmatic. I have been experiencing some back pain since quite some time now and have a doubt whether it could be associated with my asthma. Whenever I feel constricted in my lungs, the thoracic part in my back also constricts and I really do not know whether this is quite normal or not. I would like to know whether there is any method to prevent this from happening. I find that my back constricts very often and is making me experience a lot of complications due to it. So, I would be very grateful is someone could clear my doubt for me and suggest some solution for my problem at the earliest.
