I had a nasty cold just over three weeks ago. I then went to the surgery because I'm asthmatic and my chest was really bad I was short of breath and coughing up a lot of mucus. I was given antibiotics and steroids. I felt a bit better after about 4 days but this didn't last once I'd finished the meds. I've since had another 7 day course of steroids but I'm still feeling no better and I'm feeling increasingly short of breath and have a really tight chest and horrible pain in my left side and a really fast heart rate. Any opinions on whether this could be a sign of pneumonia?
