Scared. Busty girls, have you ever had this?

Question

20 years old  
Married.
Loving hubby supports my choice to get a reduction hopefully this year, mainly because of shoulder pain.
Started using bras before I even had a period.

I'm a size
30 i or 30 HH

My back = 30 inches circumference 
Fullest part of my breasts = 42 inches circumference.

I've had professionals measure and done it myself... unfortunately they ARE 12 inches.

Living in the U.K. I'm lucky enough to have proper bra sizing. America's sucks, it's the truth.

Please help me understand this, tell me about stretch marks or your experience w/ big breasts but most importantly... do you know what's going on w/ my right breast?

Answer

Looks like your bra had been rubbing underneath your breast causing scratches and bruises.

Answer

Maybe contact dermatitis? 
How long has it been there? If it's been a week or more (or if it's getting worse) I would go see a dermatologist.

I get very similar rashes from a skin condition I have but it's unusual for it to be on top of the breast. Usually in between them or under.

Answer

I'm a 36 D and I have back pain. I can't even imagine what you experience!

Answer

It looks almost like sort of chafing to me and not stretch marks . I have a 34DDD so I know how it feels to have pain and stuff and I suffer from stretch marks but I get them on the sides and they look nothing like that . Possibly your bra is chafing you ? Are you wearing too big of a bra and it's causing the fabric to rub against your boob ?
