Hi

I had something similar happen last year. I had what looked like a black mole on the back of my leg. It fell off days later and left a mark for a few days then disappeared. My dermatologist said it wasn't a mole because cancerous moles don't fall off. If you had a scab on top of a mole there would still be something very visable underneath. I'm not a dr but it sounds like maybe you had a wound that scabbed over and maybe the area is slightly swollen from the trauma. If it continues definitely go back to the gp. Good luck 

Hi Daisy,

I, like your GP and Sparkles, don't think it was probably a mole. If you've never noticed it before, you were able to pick it off and the area is now swollen there is more chance it was a blood blister & this has caused the bleeding & scabbing. You can't pick or scratch off a mole without it leaving some mark behind & the swelling may be caused by a slight infection after picking the 'blister' off.

I suggest that you wait to see what happens when the scab falls off. If there is no sign of anything underneath it was fine. If there is a pigmented spot in it's place, go back to your GP to get reassurance.

Good luck,

Angie (melanoma patient)

Hi! 
Iv literally had this experience today. 
I have never noticed the freckle sized blister before today, I went to scratch it and it just came off and now I'm panicking that it was something cancerous.

i run a fair bit, so I wondered if my sports bra rubbed or something and caused a blood blister, but you go on google and everything tells you that you have a melanoma I'm 32 years old and am panicking in the current climate as it is, this has now added to my stresses. I will be in contact with the GP in the morning.

kind regards
