Are arnica & lymphatic drainage actually bad for healing?

Hi and welcome to our forum!
Each plastic surgeon has their own unique protocol which has developed after training and a lifetime of experience. As a result, there is no consensus regarding the use of lymphatic massage and arnica after BBL. 
In our practice, I don't routinely recommend lymphatic drainage massage unless there is prolonged swelling. In my personal experience, it works quite well in this circumstance. Otherwise the body will heal itself without any intervention. I do utilize postoperative external compression to prevent bleeding and prevent fluid accumulation.
Bruising indicates the presence of blood in the soft tissues. It frequently accompanies surgery. Unless the bruise is large, expanding in size, or is associated with an underlying mass, it can be left alone and will fully resolve within a few weeks. Although I do not advocate the use of arnica, some patients swear by it.

That’s actually very thoughtful question.  During my plastic surgery training many moons ago, lymphatic massage was never incorporated into the after care regimen nor was the use of vitamins such as Arnica.  information is the body‘s natural response to trauma. It is part of the healing cascade and should not be completely subverted. That being said, excessive or prolonged inflammation can be detrimental to healing so it’s a balancing act.  i’ve been a proponent of lymphatic massage for sometime now. I see patients feeling better faster. I see patients report to me urinating after their session suggesting that extracellular fluid or edema fluid is being mobilized and processed.  do use of compression dovetails with this concept philosophically. If you twist your ankle, you don’t leave it unwrapped. You apply compression to help marshall the subsequent swelling and edema.  I do also use recovery vitamin systems including Arnica and bromelain and have an adult evidence that it does improve recovery. Several of my nurses have reported rapid improvement in bruising using both topical and oral Arnica. Having blood floating in the extracellular space does not necessarily promote healing in my opinion.please understand that a lot of plastic surgery recovery protocols are anecdotal and not based on raw science. We all have our opinions like voodoo priests that aren’t necessarily founded in some logic or science. As an aside, I outsource the lymphatic massage to outside practitioners and thus I have no secondary gain financially. In addition, the vitamins that we provide are included in the procedure price and again there’s no financial motivation for these recommendations.
