Lija is on the right track and everyone has provided good advice.

If this is Toxicosis then the bath Lija has provided will help, but you can use different baths to treat Toxing Out Syndrome. There is one that is safe, but touchy on the ratio of the mixture. Try the Electrolyte replacement bath Lija recomended and if it does not do the trick in a couple days let me know and I will recomend a different route.
