Will not wearing your compression garment at night affect my Liposuction results of inner and outer thighs?

Generally speaking, virtually all plastic surgeons recommend wearing compression garments  for a number of weeks after liposuction.  The purpose is to control swelling, help prevent pockets of fluid from developing in the space where fat was removed, and even help the skin redrape as smoothly as possible over the newly reduced fatty layer.  However, there is wide variation in the suggested time for wearing compression.  I usually suggest 3 weeks, but some doctors may suggest a longer or shorter duration.  Also, the individual patient's condition and the extent of the surgery, such as how much fat was removed, all need to be considered.  Five days after surgery seems a little early to stop wearing the garment, and if it is so tight as to cause pain, then perhaps you need a slightly larger size.  Also, 1-2 weeks after surgery is still early enough that having some slight lumpiness is common.  You might have small areas of fluid that need to resorb.  I would suggest wearing the garment and also consider discussing a gentle circular massage of the treated areas with your surgeon.  As for any cellulite appearance,  liposuction does not correct cellulite; it only reduces the bulk in a given area.  The dimpling of cellulite will often remain following liposuction.

Hard to know for certain if you ended up affecting your end results. Most likely, your compression garment routine will not have a long term affect on your results. I think that there is some scant evidence that it can limit the amount of swelling and hasten your recovery time. But I still have not seen any evidence that compression garments actually affect the end result. But this question could be debated and I certainly could be proven wrong. 

I recommend that patients wear the compression garment continuously for at least the first week post op. It can affect swelling in different places, and most times, patients share that they like wearing the garment because it feels good to keep the swelling down. It sounds like you do have swelling which will not entirely go away for several weeks. The compression garment helps to reduce the time of recovery by reducing the swelling. In addition, make sure you are getting plenty of water (not soda or alcoholic beverages) and rest since your body is still healing. If your compression garment is not comfortable, ask your surgeon for a different size. It should be comfortably snug (without leaving deep indentations in your skin). I hope this helps and good luck with your recovery!
