Is it OK to have filler 6 weeks after sepsis shock ?

6 weeks ago I had sepsis from a kidney stone I was in hospital , came out and caught Covid. I am doing well the infection is gone now but still have a stem and the stone to be remove at the end of the month . But I booked an appointment to have filler before my illness , this appointment is in 2 weeks. I am feeling fine and would love to have filler but would it be safe to have a syringe before my op ? If not how long do I need to wait ?
