Post Lipo Hardness and Stiffness, What Should I Do?

The tight bands are probably localized areas of edema and possibly early internal scarring but should diminish with time. Here are some suggestions besides simple stretching that has been recommended to you: Therapeutic or "lymphatic massage" may be helpful following Liposuction (Smart Lipo, Vaser, Tickle lipo, or conventional lipo) to minimize swelling but not all plastic surgeons recommend it nor is it Mandatory. Make sure your surgeon feels that you have healed sufficiently  and it is safe before doing this.  Endermologie is also very helpful after liposculpture/liposuction but again, not critical.  Although deep tissue massage following liposuction can aid in smoothing out  contour irregularities that invariably accompany this procedure it has limited effect on the final outcome and  is NOT mandatory. Some plastic surgeons recommend it to all  patients as they feel the edema resolves faster.  Ask your surgeon to show you or a significant other how to do this if cost is an issue. Typically they will have you massage toward areas of maximum lymphatic drainage ( for example groin or armpits) A low sodium diet and no heavy exercise especially lifting for the first 4-6 weeks may also be helpful.

Tissue fibrosis is common after liposculpture.  I inform all of my patients before surgery that they will have some amount of fibrosis (excess scarring beneath the skin) and will need to have seromas drained even though I leave drains in place to help minimize them.

Continue following your doctor's advice and instructions and things should resolve in time.
