Hi

so I've had ongoing mastitis issues, a few weeks back I went in and had a breast clinic consultant appointment and had an ultrasound scan from a consultant radiologist. They weren't concerned at all, said it was obvious mastitis. I'm still getting issues, my breast is still swollen and even my arm is a bit swollen. I hadn't even thought about my arm until I googled it and it said it can be a sign of breast cancer going to lymph nodes. How likely is it that the consultants were wrong? I feel like a hypochondriac asking for another referral. The arm swelling is barely noticeable but for example I lay on my arm overnight and an hour on I still have indents in it.
