TOS is from degranulation of mast cell that induce inflammation then fibrosis, we all know that now.

Palmitoylethanolamide stop degradulation of mast cells.

It is sell under the name "normast", in italia as a medical food.

Normast has been demonstrated to decrease pain in diabetic neuropathic pain, lumbosacral pain, carpal tunnel syndrome and nervus medianus compression pain.

I think normast = Pain free for Ntoser and minors side effects if any.

Stopping mast cell may allow a possible treatement for the fibrosis in combinaison of pentoxifylline and tocopherol.

But the problem is : It's only sold in italia
