DH has had sore red lumps under his armpits for about a month. Went to the GP who wasn't worried but has booked some non-urgent blood tests for about 3/4 weeks time.
He's now got a swollen area next to his nipple which is also red and very sore. It's like one of those big painful spots under the skin. I'm trying to persuade him to go back to the GP for another look.
Does anyone have any suggestions for what it could be? Will try to add a photo.
