My asthma has been quite bad recently, and I've been getting a lot of tightness in my chest. For a week or so now as well I have been getting a dull ache in the top of my left arm. Recently it has been going down through the whole arm and it really aches, and I don't know what it could be. The other day I also got pains in my back, though they seem to have gone for the moment. Today I've also started to get pains in my right shoulder and I'm just a bit worried about it and curious to see if anyone else with asthma has experience this sort of pain? I told my doctor about it and he said it wasn't anything to worry about, but the pain is becoming a lot worse.
