I noticed you have made a number of posts the last few days. When dealing with the unknown, it is usual to rule out the more common problems first before delving into such rare occurrences as neurotoxin.

Since another post mentioned drinking untreated creek water, and you have severe intestinal symptoms, you probably need a complete screening for water borne bacterial, viral and parasitic infections. Some that come to mind and can cause your symptoms include e. Coli, Guardia, salmonella and chigallosis, to name just a few.

It is also really important to share the location where it happened as there are many local pathogens to consider.

Have you asked to be referred to a gastroenterologist or infectious disease specialist?
