I recently traveled to mexico and in the first three days there I developed a rash that looked like bites on my feet and then what looked like small bumps on the backs of my hands. The bumps on my hands became bigger and resembled blisters, they were really itchy. Then on the sixth day there, I began having stomach cramps. Very uncomfortable - but managed to keep diarrhea at bay okay as long as I did not eat any thing. I took benadryl liquid gels for the rashes and pepto bismol ( for a full two days) for my stomach. When I did eat - the cramping returned and diarrhea returned. A full even days later, the bumps/blisters on my hands are almost gone - dried up. My stomach is still rumbling - and diarrhea each morning. The soles of my feet appear blistered now too.
