I typically can feel the reaction in my muscles in my back/shoulders before I feel them in my gut. My gut takes about 2-3 days to catch up right now. As for it being other items, I don't know. I haven't narrowed mine down to anything (maybe because I'm in denial about any other possible causes! ha), but I'm sure it's not out of the realm of possibilities.
Did you ever find anything that helped relieve the pain and itching while you DID have it? It's slowing going away, but I got glutened the other day and I have some bumps and they're driving me nuts. Can't walk without them being irritated and starting the down-to-the-bone itching!
Good to know that yours went away when you were gluten-free. I'm hoping that the longer I'm gluten-free, the longer it will stay away.
I know this sounds crazy, but you can google it and see - the BEST place to put Vicks when you have a cold is on the soles of your feet! Seriously. I don't know why but it works better than on your chest.
I do this all the time! Even on my daughter using the baby Vicks. According to SNOPES, some scientists did research to see why it works, but they couldn't figure it out. They just determined that it works 100% of the time. (Also, If you put garlic between your toes, within a few minutes you can taste the garlic in your mouth. CRAZY!)
I always find my pumpkin puree next to the pumpkin pie filling - which is usually in the same place as all the other pie fillings. There are times when it's not available and I know we went through a shortage a year or two ago, but it's almost always available with the other pie stuff.
If you can find Libby's pumpkin, get it...and then make a pumpkin pie using the Libby's recipe on the can. Super good!
