I've been having some concerns after getting the Covishield vaccine a few days ago. I've been experiencing chest pain and a feeling of tightness, along with mild difficulty breathing when I'm lying down. There's also a lot of mucus coming from my mouth. It feels like I might have a cold, considering I've had COVID before. Should I be worried about possible chest congestion or could it be something else?
take one mucolytic for 5 days twice a day
