Oh no! I hope there aren't any lasting effects like shortness of breath or not being able to smell or taste anything, because I've seen some "long-haulers" say they're still unable to exercise months or a year because of the damage to their lungs. A friend of mine that also had covid is using a lung resistance training device called a PowerBreathe to help him get his stamina for exercise back. He told me it's working very well for him get back to where he used to be, though it's probably more for people that had less severe cases. It could be of some help in recovery, but I don't expect it to help with things like fibrosis or any other serious lung damage.
