I am so sorry to hear your problem is continuing. I think it is important to find out what is causing the shortness of breath it can be many different things If you are having an embolism, they can give you medication to breakup the clot, and some oxygen to help with the shortness of breath. If you are having an occulusion, they can break up the occulusion and perhaps place a stent, if you are having Atreial Fibrillation, they can give you medication for this problem. As you can see this is only a small number of reasons for your problem, and they all have medications to help the problem. Please seriously consider seeing your doctor tomorrow.
