Muscle pain and sore legs n buttocks after fat transfer, is this normal?

This may not be anything of concern.  I would obtain a cardiac clearance prior to surgery. Find a board certified plastic surgeon who performs hundreds of Brazilian buttlift procedures each year and produces the results you would expect.Kenneth Hughes, MDLos Angeles, CA

Do the benefits outweigh he risks? In your case no.  Complications would be life threatening.  Safety first.

Practically speaking for your job position two to three weeks of recovery would be recommended to my patients undergoing a Brazilian Butt Lift

Thank you for your question, I would recommend to ask you plastic surgeon directly, most of the times your Doctor will provide the garment, its best to use the one your Doctor suggests to achieve the best possible results. Also After surgery your body is very delicate, so any garment with wires...

You are asking for too many procedures at one time. I would start off by doing your fat transfer and gluteal shaping. The next surgery I would do would be your breast augmentation tummy tuck. The last surgery I would do would be the thigh lift. Earl Stephenson, JR, M.D., DDS, FACS 

I would make sure that your infection is under control before having surgery as this can increase your chance of surgical infection.  I understand the contraindication for warfarin, but not amoxicillin.
