Thanks for writing to us.
The small pea sized lump you are now describing is in all likelihood, a small heamatoma due to oozing of blood from the leaking arteriole/venule
supplying the benign papilloma.The supplying blood vessels are usually ligated and then the papilloma will be excised in a conventional procedure.In Laser
Removal etc.,they may be using a different cauterizing procedure with or without ligation.Hence the haematoma
formation.It may be self limiting also.
kindly wait for a few days and the clot will dissolve by itself as the body's fibrinolytic mechanism shall take care ,then it will be called self limiting.
If the lump increases in size, kindly go back to your MD for intervention.
Wishing you a quick recovery..,
Dr Lt Cdr ASN Bhushan.
