3 weeks since 2nd vanquish treatment and I still have hard lumps in my abdomen. WIll these go away and can I continue treatment?

This is fat necrosis and these are lumps of fat dead cells, so that is a good thing.  It is okay to resume  your treatments as long as the tenderness has resolved.  There are things that can be done to prevent this from occurring again or worsening though, namely.....1.  Be sure you are very well hydrated with at least 64 oz of water daily before and after treatments, 2. Cellutone treatments to the area after each Vanquish ME treatment if your doctor has it available (or other vibratory type treatment to help break up the dead fat cells and move them to your lymphatics) 3.  Be certain to tell your provider immediately if you develop any uncomfortable hot spots during your treatment so adjustments can be made as this should not be an uncomfortable treatment.
Your lumps will go away.  It will just take time. And you will be thinner.

This condition is seen occasionally . It is due to the fast lysis ( cell death) of the fat and is called fat necrosis. It subsides after a couple of weeks and you can resume treatments. It shows that the treatment works, almost too well in these cases.. It is not a concern. discuss it with your physician.Ahmet R Karaca MD
