Tightness after arm lipo. What can I do to help it?

Swelling after an armlift can last up to six months or even a year.  Induration and hardness are components of the normal healing process.  I usually provide compression garments to my patients which cover all of the areas liposuctioned.  The patients who tend to have healing issues with liposuction procedures tend to be the ones who do not wear the compression garments at all, wear them very inconsistently, or do not wear them snugly covering all areas of liposuction.  
Post-operative protocol varies from PS to PS, so best to follow your PS 's guidance.

Hello dear!!
Thanks for the question and provided information as well.
You are still early on the healing process, it can take up to six months to see your final results, so please be patient. At the stage you are in, inflammation and discomfort are normal.Try soft stretching exercises, two or three times a day, with your doctor's blessing. 
If you have any concerns, please follow up close with your plastic surgeon.
Good luck :)
