I had an episode of pneumothorax 4 years back , that was primary spontaneous pneumothorax which resolved within a week by the help of oxygen cylinder, but still even after all the normal ct scan and reports, i face breathlessness and chest pain specially in right lung when i lift heavy objects which requires extra effort and even i ran out of breath when i carry 1 or 2 kg of weight for so long , why is it happening, will it be for lifelong ?? It's about my life ...
