This is the second episode I have had. It begins with uncomfortable, severe itching of hands and feet for about 25 minutes, then cramps, ears ringing, sweating, extreme diarrhea, I become pale, have increased pulse and extremely weak. The first episode included vomiting as well and lasted about 3 hours. Tonight's episode only lasted about 2 hours. After the symptoms, I feel completely fine. What kind of doctor should I see?
