Milk blister

I recently got a milk blister (omg it hurts like hell) and was still feeding my daughter from the side it's on. Recently she's starting to refuse nursing from the side with my blister and will nurse on the other for a little and then eventually refuses to relatch after a good 5-7 minutes. She does take down a bottle with no problem though. I'm of course going to discuss this with her doctor in a few days but just wanted some of you ladies opinions. Do you think she's refusing because of the blister or maybe just weening off. BTW she's 6 months.
