Is it possible for an inverted triangle body shape to turn into a pear body shape from a fat transfer?

SO don't worry, anything you have had put in, added to some swelling post op will feel tight at day 2-7. As long as it isn't hot and red and painful then go with it. Once the swelling starts to fade things will feel a lot more normal but don't expect a soft contour for 3-6 months at least....

It would be better if you would do a thigh lift. This would give you the results you would like to achieve, fat transfer will only make your thighs bigger. 

SO liposuction always leaves an uneven result in the early days. Massage helps squeeze out the fluid that has replaced the fat globules and so can make the results smoother in the short term and speed recovery and the final results in the medium to long term. Don't excessively massage the areas ...
