1. Im re-posting this in this forum to see if anyone experiences these side effects years after mastectomy.
   
   Hello, it's been 3 years since my diagnosis; I'm 46 and starting to have pain in various areas. I know nerves can regenerate and cause searing pain, and tbh... I've been calmly dealing with it. However, today I found a small bead-like bump near my first excision site. Cue anxiety.Regarding pain... it started out in my left buttock. Not a typical sciatica pain; but almost like a bruised feeling. That started 5 months ago and is mild. It hurts when I sit or move a certain way. No big deal. Then came the pins and needles on the same leg. This November I started getting those sharp nerve pains in my back. This last week I started experiencing sharp stabbing pains above my right ear on my scalp. Pickax style. Two days ago, my middle back locked up and I was in excruciating pain for 5 seconds. Yesterday, it happened a 2nd time. It was terrifying. I've never had back issues in my life. And today, an area on my breast kept itching (more than usual) ... so I sat up to get better feel of it, and there's an oval bead just under the scar. It's my old lumpectomy scar ... not my mastectomy scar. I've got an appointment with my GP in February for my back/butt/nerves... etc. But now I'm freaking out about this bump. Has anyone gone through similar symptoms? Hoping I'm just getting old and having aches and pains.... in the geriatric kind of way. And NOT in the cancer recurrence kind of way.
