I am a 58 yr old woman who on this past Friday afternoon I began feeling stomach sick and between about 1:oo pm and 8:oo pm I vomited about a dozen times and had multiple episodes of diarrhea. On Saturday I pretty much slept off and on, and had only a few times of diarrhea. I tried oatmeal for breakfast that day, but nothing else. Sunday I was able to eat bananas, rice, toast. This morning I had oatmeal and just now some chicken soup. One time of diarrhea today. I continue to feel, just not right . My stomach is doing some flips. I am beginning to wonder about something. ... On Friday I had noticed a swelling in my middle left finger, at the tip, like a hangnail might give. but no hangnail. No fever. Could I have an infection in my finger that is making me feel bad? It really hurts and is swollen.
