My coughing fits

I suffer from Asthma, but it is controlled and normally is only affected by animal contact.  For the last week I have been waking up during the night choking and can't stop coughing for anywhere between 30 mins and an hour.  I feel like I have something pushing in the bottom of my left rib or lung and it is painful.  It is really wearing me out and my puffers don''t seem to help.  During the day I still feel like there is something not quite right, that something is there below the rib on my left side and I can feel it when I lie down flat, although to the touch there is nothing.  Should I be worried about this?
Thank you for your time

If this is a change in your symptoms that is not easily taken care of by an increase in your medication, it is probably a good idea to be seen by your physician. It is impossible to know what the discomfort you are experiencing under your rib without someone examining you and perhaps performing an x-ray. There are several reasons this could be present. The safest thing for you to do is to be evaluated before this gets any worse.
Good luck.
