I didn’t drive for awhile after my partial mastectomy, for one thing it was my left side and all our cars were manual, also if I had to brake heavily for some reason I did t want the seat belt to go tight over my chest which was still recovering from surgery.
I had to use a pillow under my surgery side under armpit for awhile as just going over a bump wasn’t pleasant. We live out in the country so the roads probably aren’t as smooth as driving in a residential area, every trip to a specialist I was in the car for a minimum of an hour at a time.
Didn’t even check my insurance as I was fortunate to have my husband home so I didn’t have to drive .
listen to your specialist, your body and I would probably check your insurance.
Hope your recovery is quick, sending gentle hugs xx
