Is it too soon to do revision on my nose 1 month after removing the implant, only 4 months after the original rhinoplasty?

Rhinoplasty done on 12/9/13. Doc used Goretex (bridge) & cartilage (tip). 1 month after, redness appeared on the bridge. I asked Doc about it & he prescribed Augmentin for 7 days. The redness persisted so he scheduled the removal of the implant on March 10. Doc says revision is okay 1 month after. He will use my cartilage this time. Isn't this too soon? I'm happy he's willing to redo everything without charging me extra but I'm wondering if he's being too aggressive. Please advise. Thanks!
