7 year old blood blister.Treatment options for removal?

[Glutonfreenongmo]

I have a blood blister that I discovered at 16. It was small (about the head of a pin) when I first found it. I popped it, thinking it would drain and heal. Over the years, with each popping, it has grown to about the size of a pea. It's been here (on my middle inner thigh) for 7 years now. It's not painful, but if it's rubbed, it pops and it bleeds a lot, for 30 minutes at least.i have varicose veins, so I know my veins are not circulating well. It's an eye sore and makes me avoid shorts or dresses, so this year I want to get it removed. I don't know the technical name for it, or the treatment options, or the cost for said treatment. Please, any advice would be helpful!I feel like the only person that's ever had this!
