I am 19 years old. i had done my ct scan and found that i have bilateral resuidal belbs on lungs which can cause pneumothorax. and i feel little shortness of breath. so how can i reduce those resuidal belbs on lungs. please suggest me best medication?

The only way to remove blebs is surgically. However, if the blebs have already been removed, then what is left would likely not be enough to cause a pneumothorax. The doctor who knows that for sure is the surgeon who removed your blebs. You should see that doctor to be certain there is not enough blebs left to cause a pneumothorax. So, see your surgeon for a follow up visit. Good luck!
