How Can I Get Rid of Scar Tissue on my Inner Thigh?

Soon after liposuction there will likely be lumps and  bumps and skin will not have taken up fully.

To help resolve these issues massage of the area will encourage swelling to resolve and the skin and scar tissue to retension and soften.

It may take months and even up to a year, but the situation will improve and the sensation will return

Get massaging I say

The after care following lower extremity liposuction typically involves wearing some sort of compression garment to balance the hydrostatic pressure of the body in the areas traumatized by the surgery.  12L is beyond the 5L recommended by the Amercian Society of Plastic Surgeons liposuction committees when performed as an outpatient surgery.  Essentially, it is a lot of healing for your body to accomplish, probably in a lot of different areas.  I would recommend wearing the garment all the time in addition to hand massage, vibratory massage and/ultrasonic massage to the lumpy areas.  Seven weeks out should still be timely enough to affect these areas of swelling irregularities, especially if they are still sore.  I would also recommend a followup appointment with your surgeon.

Scar tissue after liposuction is not common. If you are feeling lumps, then you might want to cosnider massage to help soften them.

There are a number of modalities that can help (massage, ultrasound) but only with an exam can a sensible recommendation be made. Your surgeon will be a far superior resource than can be an online surgeon who has never seen you. 

I might add that most surgeons feel that 5 liters of suctioning is the maximum safe volume to remove at one setting. I would be suspicious about a surgeon removing as much as 12 liters. Perhaps a second opinion would be in order.
