Cankles-McJeggings There’s various causes, mine has been attributed to foreign body implant rejection leading to autoimmune disorder. (Poly Hernia guaze which I had removed because of it)
I can imagine that - since this issue developed I also sometimes have mild allergic-type reactions to some types of polyester clothing.
Cankles-McJeggings Most have no idea or indication as to the cause but it’s getting more prevalent and highly likely to be connected to use of pesticides and GMO.
As per the point above, wouldn’t be surprised if the chemicals from plastics will also be a causal factor in its increase somehow.
I think generally it will be anything which has the potential to trigger autoimmune issues, and/or things which mess around with your normal gut biome e.g. antibiotics, some antidepressants.
