Sickness. Nausea and obvious sickness are also those two symptoms that will appear earlier than others. No matter how fast your rash is developing, you may feel the sickness in the earliest stages of shingles. The sore stomach will be followed by nausea. This symptom people often mistake as a simple food poisoning. But when your sore stomach is followed by diarrhea and vomiting, you should consider shingles as the main reason.
Fever. Nausea and fever will usually come at the same time. Misery loves company, as we know, so those two will come together. Sometimes there can be even no actual rise in temperature, but a patient will feel like it is. But the real fever caused by shingles may raise your body temperature up to 101 degrees F.
