Burning in chest after mastectomy

I had burning pain in my chest m, not associated with sex really that I could tell. Have you also had radiation?

I have not had radiation.
I have burning in my chest often still ( I'm 8 weeks post op from double mastectomy). I didn't necessarily feel burning right before sex, but the burning was very strong immediately after my orgasims. It definitely felt related.
Maybe it's a sign I won't lose all feeling in my breast? 😉
