 [ Symptoms ] 8mos old son had a fever for 4 days used ibuprofen & it is now gone but he is constantly fussy which is not his norm  a week ago my son had a fever when i got home from work we used acetamenophen and ibuprofen to treat it had more success with the ibuprofen during the 4 days he had his fever he was miserable did not eat well or sleep well which is to be expected now the fever is gone and he is still miserable   we returned to the md to see if he had something going on like & ear infection & were told he is fine   before this he was my happy little guy &now he is miserable and fussy no matter what we do [ Disease ] finding the reason or reasons why a child is fussy is always a clinical challenge it could be teething remember that you can treat the misery with ibuprofen he does not have to have a fever to use it if his mood improves after a dose of ibuprofen you may have fixed the problem children get tummy aches headaches backaches or get in crabby moods the only problem is that they can not tell us make sure he is using all of his limbs especially his arms eight month olds can get accidental elbow dislocations if you pick them up by their arms check for diaper rashes and make sure he is eating and hydrating well
