Dont know were to post this

So the last couple days I have this bump on my inner thigh * overweight so my thighs do rub together* well it wasnt really popping out like it is now.. It feels squishy like a giant pimple. Its hurts so much to wear shorts bc my skin is in contact eachother so it rubs against it.. What do I do? Do I try to drain it or let it go on its own..
