I started with stiffness in my arms a few weeks ago after radiotherapy to my left breast noticed it when I was putting my coat on. Last few days I have been getting worsening pain in my left arm sometimes travels from my shoulder to my hand and my bone been cracking when I do my exercises and makes my arm hurt. Last night the pain was going into my neck I struggle to fully lift my arm and it's worse at night when I'm in bed. Told my Target therapy team who told me to ring radiotherapy team now they telling me ring breast nurse feel like I'm always being pulled from pillar to post!! Just wondering what this could be? I had lumpectomy in November and had a few lymph nodes removed and there is still lumpiness around my scars and get the odd twinge under my arm too.
