Bj after surgery

Weird question and one I know most people will say they probably can't answer but I'm going to ask just in case anyone here has done this.

How long after having a tonsillectomy can I give a blow job do you think? hahha

Due to my issues with my throat I haven't been able to give one in a long time, and want to do it for him again. It will absolutely be gentle and I am in no pain.

Again, no worries if nobody knows but just going to ask! haha
