My two daughters, age 8 & 4, both are complaining of headaches . My 8 yr old saying her brain is jiggling when she moves. The also have neck and leg pain and stomach aches when trying to eat. I just took my 8 yr olds temp because she said she feels hot on the inside and really cold on the outside, it was 96.8. This has been ongoing for a few weeks now. I have been writing it off as ways to get out of things they don t want to do but when my 4 yr old started crying of her neck hurting while playing soccer, that she loves, I m getting spittle concerned now.
