Well I made it! It's Friday and the process is over and I've had a shower, which felt amazing after a week without.
It depends on your view point as to what you think of my results. I wasn't contact allergic to any of the 114 chemicals I was tested for. That's good news, I have enough allergies to contend with as it is. However, the consultant has confirmed what I suspected all along and diagnosed pompholyx or dyshidrotic eczema. He couldn't suggest any cause for it and advised that the only thing was to treat it when it flares up.
He wasn't very open to discussing other possible causes of the eczema. Luckily I am without a flare up at the moment but I have no way of knowing when if might happen and no way of trying to prevent one. Not the most satisfactory outcome.
The patch testing process was certainly interesting and at worst it was uncomfortable. I still have some sore patches were the tape irritated but that will soon heal. If you are having the testing soon it's really nothing to worry about. Good luck and let me know how you get on!
