What Causes The Fontanelle To Raise After Running A High Temperature?

please my baby is 4days short of being 6months old.he has been very active but started running temperature and has some rash on his chect which i thought was due to heat and makes noise as tough he needs something. At times he contract as if he wants to defecate while sucking but will not and when he does, it is with much pressure trying to force it out but my greatest worry is that he s fontanel(soft spot) became raised instead of the slightly depressed look with high temperature.

Pediatrician 's  Response
A bulging fontanelle occurs as such with high temperature, this is because there is increased blood flow to organs, also called a hyperdynamic circulatory state. But prolonged fever with dehydration will result in a depressed fontanelle. 6 months old child with a fever, rash, feeding issues and irritable cry it is always essential to rule out an infection in his brain.
