2week pathways for breast cancer

Hi, I’m 32 mum of 4 children, I noticed my right nipple was look ‘different’ ever so slightly but definitely different, thinking it was nothing to be concerned about I ignored it, fast forward few days a red mark appeared on my right breast/nipple, mum made me go to gp who examined and has decided she wants me to be seen at the breast clinic for testing, she did say she couldn’t feel any lumps in my breast and squeezed both nipples and no discharge of any kind, I have an appointment for this Thursday, my other symptoms are nausea, ridiculous amount of sweating, loss of appetite, right shoulder aches and fingers keep going tingly so trying to convince myself it’s just a nerve issue and the dr is just being safe than sorry (so grateful for) but waiting till Thursday I feel is making my anxiety go through the roof, has anyone else experienced these symptoms had testing and turned out to be nothing? Probably the wrong question to ask, but I feel like the wait is going to make me go insane thanks in advance
