Is it safe to get a tattoo on my thigh after having rhinoplasty and taking some muscle from my head under the skin to fix my nose 7 days ago?

Wait: I would let yourself recover fully before you have another "procedure" ...6 weeks.

Yes, but why risk it: There is probably no contraindication to getting a thigh tattoo one week after rhinoplasty, but it sounds like you had a temporalis fascia graft with your rhinoplasty, which you wouldn't want to increase the likelihood of getting infected, although extremely low. These are cosmetic treatments, so i would always ask my surgeon prior to doing something like this.

Wait: I would wait until healing is more complete, and your surgeon clears you.

Rhinoplasty: Having had a rhinoplasty does not preclude you from undergoing tattooing.
