Is it normal to have sharp pains in the breast and upper back post breast cancer surgery?

Post surgery neuropa: This is likely normal post surgery. You are described post surgery neuropathic pain. This is typically a result of "cutting" of the nerves in your skin from the surgery. Most people will have improvement over time, but some will have continued pain in the region. Some patients have "phantom" pain post mastectomy because their body still thinks the breast is there, even though it was removed.

Maybe: Healing after surgery will take some weeks, and pains during this time of healing are common. Sometimes referred muscle pains can go into the back. Watch for increasing breast swelling or redness that would need to be evaluated by your surgeon.
