I was training for my first sprint triathlon until getting hit by bacterial pneumonia about 6 weeks ago which took 2 lots of antibiotics to shift. I wasn't hospitalised but still have some pain in the right hand side of my chest. Xray is clear, but still very breathless. The triathlon is in July and my mind is really willing to start running again. I feel overweight and need to start exercising again. But my lung capacity feels bloody awful. Has this happened to anyone else? Any advice? I was starting from zero fitness to begin with, but felt so good until this happened. I'm desperate to start training again but have no confidence in my lungs. I went swimming with my little boy today and struggled to breathe properly just swimming for fun.
