I've been having really bad shortness of breath and this tight feeling in my chest, especially when it's cold and rainy like in November and December. I've noticed it's happening a lot more often, like almost every day now. I can't sleep in the early mornings because I start coughing and sneezing, and then immediately feel out of breath. I usually take Seraflo 250 and it helps for a bit, but I'd really love some advice or to know if theres a better medication that might help me deal with this. Any suggestions?
