On and off throbbing pain, burning sensation in left boob after first “real” post op workout

Hi! I’m currently 6 days shy of my 2 month boobaversay, being 2 month post op I have been listening to my body in the gym and taking it relatively easy. Yesterday was my first back workout since my operation and as the day progressed I had a on and off throbbing in my left breast as well as some burning sensations. I know i’m early in my recovery, and that nerves and stuff are coming back but should I be concerned? I did not feel any pain during the workout. Thanks!
