Stopped sweating from armpits after surgery

I'm not too concerned about this but I'm curious if others have had this experience. For context, my incisions go all the way back under my armpits bc I had a lot of side fat. Most of my numbness is in my armpits. Additionally, I have not sweat from my armpits since after surgery, and no BO coming from them either (no nips so I've already been able to shower a few times as well). And usually I'm a SWEATY mf. I'm on multiple meds including testosterone that cause increased sweating. I literally sweated through my hospital gown in pre op within ten minutes of putting it on, and I wasn't even hot! I sweat when im cold! Has anyone else had a similar experience? Do you think it's related to the nerve damage causing the numbness? I have sweat from other areas like my neck and knee pits so I'm not worried about overheating due to not sweating from my armpits lol. Just kind of a weird thing that I've never heard anyone else mention. I'll probably mention it at my post op visit in two days.
