Got a bump on two different places

[Bujiarong]

I got a blister on two opposite sides of my body that won't go away, I popped it before but it grew back

Maybe they weren't blisters.  It's never a good idea to 'pop' things on yourself because you could infect whatever it is.  And something recurring might be worth getting checked out.  I'm not sure what is going on other than if you get blisters in the same spot, look at what could be causing the friction.  Shoes, for example.  My son gets a blister in the same spot every time he has a soccer tournament, plays more than one game in a day and it's wet or raining.  Which sound strange to know this but it has happened three times in spring.  So, we now know on those occasions to put a barrier like mole skin over the spot, change socks frequently and that stops it from happening.  So, not sure where your blisters are but look into the why it would recur.  good luck
