A member asked:

My dad has a growth on his arm. it looks like a bubble. he tried to pop it but nothing but a little blood came out and it got swollen.

A doctor has provided 1 answer

He needs to be seen: I can't be sure what the blister was without seeing it. If the area is swollen it could be a skin infection and he needs to seek treatment.
