I read the entire article and interestingly enough, I’m thinking we experienced something very similar to this perhaps ten years ago or so. It is a very unpleasant problem and if coupled with any semblance of a sunburn, it can be totaling debilitating. First day or so I tried otc topical solutions but finally gave in and went to the doctor.

The recommendations included carefully washing the effected skin areas with a good skin soap and thoroughly laundering all swimwear I might have worn along with the strong admonition to avoid the ocean for a few days. Back then we stuck to pool swimming only for the balance of our trip since we were never sure if we picked up the problem at Mullet, Simpson or Friars Bay beaches and we didn’t want to take any more chances once it calmed down. The medication that was prescribed helped take the itchy-bunny feeling away and within a few days all was good again.
