Fever 102.7 Day 1 & 2. Day 3 & 4 seemed fine. Day 5, headache. Day 6, stomach ache, threw up 1x, headache, & took 3 1/2 hr nap. Negative Strep test. Day 7 seemed fine. During night complained of headache, throat hurting & by morning (day 8) fever of 100.3. Dr said wait today & see how it goes & if still persistant, see dr tomorrow. Now has complained of neck hurting a few times... maybe from just laying on it... took 3 hr nap. Any ideas?
