Persistent swelling vs. still too big
Swelling increases for a few days after surgery, then gradually (over many months) will subside. Unfortunately, on occasion, the swelling can convert to scar tissue and persist as thickening which is particularly noticeable in the tip region. Sometimes, injection of steroid medications can be useful (although this is usually done more early in the process). Regardless, I would recommend waiting a full year before considering any kind of revision as some people take longer to completely heal.
