Let me be frank, I am not an expert on allodynia though after searching madly on the internet to find why I couldn't wear a shirt or a breeze across my back paralyzed me in pain, I diagnosed myself. I told the pain management people about & it seemed as though some of them had never heard of it! I swear some of them just think we're wussies. In the last month and a half to two months I cut *way* down on my salt intake, which used to be quite high & at the same time my allodynia began to get *much* better. I didn't notice a correlation until yesterday when I ate something extremely salty and today the allodynia is as bad as it ever was. The salt was the only correlation I could think of and so that's what I searched and I stumbled upon an article in the Journal of Neuroinflammation about the effect of salt, here is their finding in a nutshell:
"Mice on an high salt diet have reduced mechanical thresholds. They feel more pain than those on a normal diet"
