I did a skin test last night. Put some sea salt in my hand, added a little water and rubbed it on my right wrist. Did the same thing with table salt on my left wrist. Sat down to watch tv. After a few minutes, my right wrist started to itch and some red bumps appeared. Left wrist was fine.

This weekend I will try ingesting it.

If this is a problem, I know it's not the salt. It's the "sea" aspect that is potentially the allergen. And fwiw, although I would like to find a cause for the allergy I do not want to be allergic to sea salt. It will be hard to avoid. Even Wendy's is starting to use it on their fries.
