Boobs and back pain?

Matty

Hey, so over the pandemic my boobs have grown... a lot. I went from a D cup to now a G cup (DDDD). And I’ve also been working out and dieting and have lost around 20 pounds from my midsection, in my stomach and my waist.

But I’ve been having a lot of issues with pain in my lower back, so do you think it’s just my boobs?

Should I get it checked out?

I’m 15 btw Idk if that makes any difference
