I think it will be okay to wait. I know the whole thing is just a nasty wound and it will probably clear up. I think if you know it's getting "worse" you should go earlier but it just takes a bit to heal. I would just keep it clean like you are doing and don't strain too much to cause it to oooze.
I too had this and I put a pad on it to absorb anything that came out to keep it dry so it could heal... (dr. suggested)
~>Use Bacitracin ~ it's WAY better and it's for scars (and TATTOO's) ~ heals it faster ~ ... it's been a while since I had mine (11yrs) ~ do they still give out those elastic belly belts..??..~if so, don't use any bandages ~ just put the bacitracin on and the belly belt to it can heal naturally....the bacitracin will heal it and prevent the belly belt from sticking to it ~ BEST OF LUCK!!!!...remember, take it easy ~ !!
Thanks ^_^ They didn't give out a belly belt but I did go and bought some non-stick pads. I haven't heard to use bacitracin, I'll have to go and look for that tomorrow. Thank you everyone for your input, just going to keep it clean and dry and see the doctor on Wednesday as scheduled.
