Recovered from COVID 3 months ago. Initially chest used to feel very heavy and there was numbness in the left hand also. Palpitations were there so I took corbis 2.5 for 10 days. Now palpitations are okay but heaviness still remains. The intensity of heaviness have gone down but whenever, I work out or lift something heavy, my chest becomes heavy again. Tests done on 29th august- ECG, ECHO, D-dimer, CK-MB, TNI, BNP, MYO, chest x-ray and PFT. All were normal. Sometimes when I press my chest (right/left) , I feel crackling sound like when you crack your finger. What to do?
