Cathy, Do talk to your onco team. I am 5 years out from radiation and still have sensations at times. Under my arm where node was removed, I sometimes get hours of a sort of sidewalk burn feeling. I still get sharp sudden pain in area of my tumor surgery. And I also have tangeletasia in the area of my tumor removal. No pain with that specific but definitely colorful. 😏 One of the annoying things about treatment is not knowing what to expect when symptoms arise and usually in my experience those symptoms arise on Friday nights when my onco clinic isn't open until Monday. I don't want to talk to the on call onco because it really isn't an emergency. It is just scary and annoying and, dammit, it hurts! Then my oncologist told me that it is most important to report every symptom. It is not a complaint but rather a report. Important thing is to not panic and do not let this keep you from whatever stretching exercise has been recommended to you. I promise gentle stretching does help.

Wish I would have known all this before I had radiation. I’m so upset I couldn’t scream. I hate this pain!!! Can’t sleep. This is not the way to live. My family does NOT understand what I’m going through!!!

Is it unusual to have toothache-like pain periodically in your arm on the treatment side after breast cancer surgery and radiation?

Actually, nerve-related sensations in the arm and chest area aren't unusual after breast cancer treatment. Radiation can cause nerve damage, leading to various sensations including:

- Sensitivity
- Numbness
- Pain
- Tingling in the chest or underarm areas

This happens because treatment may damage nerves, but your brain still sends signals to those areas. Some people describe these sensations as electric shock feelings, burning, or shooting pain.

The pain you're experiencing could be neuropathy (nerve pain), which is a known side effect of both surgery and radiation therapy. It can show up as different types of uncomfortable sensations that might feel sharp or unusual.

That said, it's important to report this symptom to your cancer care team. They can assess whether this is a normal part of recovery or if it needs further evaluation. They may want to ensure there are no other issues like infection or other complications from treatment.
