Housemaids knee - Busitis

One of our fighters has developed Bursitis in the knee, commonly called housemaids knee.

A few years ago another one of our guys suffered the same and a fellow forum member suggested a home remedy to draw out the swelling.

It involved using a common washing product and wrapping the knee over night. Somehow this product drew the fluid out.

Anyone know what this is?

Thanks in advance.

Post on the Australiasia forum, i believe geraldbb has commented on a similar process there.

Rest and ice are best for treating bursitis, which is a repetitive strain injury causing swelling of the bursal sac.

Washing products will not draw fluids out of the sac.
