Got a Medical Question? Ask a Doctor Online!
Hi. Welcome to JustAnswer. My name is Uzair.I am reviewing your post and will get back to your reply momentarily.
Most likely the blood is due to abrasions in the throat due to the constant coughing but hemoptysis is something that should not be ignored and I suggest you see a doctor as soon as possible today in the ER or the Urgent Care. Cardiac events need to be ruled out specially in the light of your history of ablation.
