What is this lump?

Sh

I often get these big lumps on my inner thighs. Sometimes they’re this colour, some times they’re red. I’ve been to 3 doctors and have had no luck. I have popped one before, lots of blood and puss comes out and it leaves a hole and a scar. I can feel a lump under the skin and it’s painful but not unbearable. I really don’t think they are cysts as I’ve had a cyst before and it’s not the same. Please help😩
