Four months ago I got very sick and it came on quick! I had all kinds of test and they came out negative. Final diagnosis was a bad virus. After 12 days the most severe symptoms were about gone. Today the similar symptoms appeared. I am in CO and live in MA. I am pretty sure it is dehydration, but my symptoms are different than the ones listed. They include dizziness, some stomach issues, shaking and numbness. I do have MS, but the numbness was more than usual. Having difficulty get legs to move. I am currently drinking plenty of fluids and feel a bit better, however not sure what else I should do. This did happen one other time in MA about three weeks ago, but was fine in about 5 hours. Thanks
