As far as the other subject that you mentioned Doctor the negative pressure therapy again a supplemental treatment.
If you have a wound and you have things growing on the outside of that wound and you have fluids that need to drain off then a suction device placed on the wound we call it negative pressure therapy can be applied and suck off all of those unwanted fluids.
A side effect of the suction device is that it tends to make blood vessels grow into the wound because of the physical forces exerted on the cells.
Negative pressure therapy sometimes we call it vac therapy is also a useful adjunct and I would classify it as a useful tool as a supplement in wound care.
All the tools combined help us to get the job done. So none of these things that we are mentioning are unimportant but silly as it sounds I kind of think the most important thing is the diet.
Eat the sardines not the cereal.
