I have the exact same thing
Did you find a cause
Omg I am relieved to find someone else with this issue. After my husband giggled at me about this weird issue I told him other people have got to have this issue. We searched and came upon this. So glad Im not the only one. Mine is a tad different though, in the way that my feet are not affected and I can usually touch dry things as well. My issue usually comes after washing my hands or doing the dishes or taking a showe, my hands feel extremely dry afterwards and I cant touch anything until I put lotion on because if I do it hurts my two front teeth. Sometimes this even happens when my hands dont get wet, they just randomly have a different feeling and touching anything hurts my teeth until I put lotion on. Ive used the same example to try and explain this to my husband, its like nails on a chalkboard. Nails on a chalkboard has always hurt my teeth as well.
I have experienced the exact same thing as this my whole life. The hands feel and teeth sensitivity all simultaneously affects one another for me . I too would describe it as nails on chalk board. I would describe my sensitivity as pretty extreme as well. All different types of textures bother me. Foam boxes paper. Anything that creates a drying sensation on my fingers And my feet actually. It makes me weak feeling. Like a person sensitive to the sight of blood. I get that feeling. I know that if there were some type of cure or even just a treatment that it would improve my life significantly because I suffer with this daily. It affects my everyday living. I will opt out of different activuties because of these symptoms. I would go as far as saying it's miserable honestly. It creates a lot of anxiety and stress for me.
I have to admit that I am a smoker and was using Ranch filters which must have a lot of bleach used in the process.
I have changed brands and the problem went away.
A girlfriend of mine had the same problem, but she worked out that it was caused by tea bags.
She has changed to leaf tea and the problem went away.
Good on you for making the connection to bleach!!
It is the answer to the problem I think.
Tampons could also be an issue.
Just a thought....
I deal with this too and it's pretty debilitating. For me it's my nails not really just my hands and feet. I actually had to wear gloves today because it was too painful with the dry air and it wasn't even cold. My teeth scream if I bite into something dry like bread as if it was a dry sponge. I also can't eat ice cream much anymore or anything too sweet. Or drink cold water. Anything dry or too hot or too cold is just painful. I moisturize all the time and use special toothpaste but nothing helps other than wearing moisturizing gloves and socks. But I feel ridiculous wearing gloves in the spring. I searched and searched Google but nothing has come up. When I try to explain it to people I tell them it's like nails on a chalkboard or like frostbite. It's so painful. I can't even use hand dryers in public bathrooms without cringing.
