Hi, I hope someone can help. I have had a lump on my right upper arm for a while now (beginning of 2020?) and I left it for a while (didn't have any other symptoms wasn't too worried and lockdown!!). But I finally went to the doctor and I have an ultrasound on Friday this week. With this lump I've had the odd feeling of soreness in the arm/numbness like it's falling asleep and I have to wake it up?! These feelings are becoming more sore and are happening more often. My fingers/hand are achey. I also have very very tender/sensitive skin on that side? On the side of my torso, the back of my shoulder? I am also incredibly itchy but mainly on my back? I don't know if any of this is related but I'm driving myself crazy googling all of this and seeing saracoma's being the answers! Has anybody had a similar experience and can help give me some peace of mind or some honest advice? Thanks so much. First time posting on here.
