How can i recover my lungs post covid-19. shortness of breath during exercise, cant run as much as before, i feel my lungs have become very weak. are there any herbs or medications to heal my lungs naturally? (i dont want inhalers), thank you?

You can get pulmonary rehab, a gradual exercise program meant to increase your lung capacity. Your doctor can refer you for pulmonary rehab. You should also find out if you need supplemental oxygen therapy, even if it is temporary. If your oxygen level is too low when you move around, it will be less likely to happen. See a lung doctor for full evaluation and pulmonary rehab referral. Good luck!
