Teething fever When to call the doctor!!!!

Johanna
My baby will be 6 month on the 26th, on Monday I took him to the doctor for a check up everything was fine the pediatrician told me that he was teething but last night he started to have some fever than went for 104 I put wet socks to bring down the fever it worked for a little bit then started with up and downs he was sweating cold so I changed his clothes probably 3 to 4 times he vomit twice so not sure if this is a leap, growing spur, teething or something else is killing me not knowing what's going on. Right now temperature is 100.4 also I read that when teething is happening the temperature does not reach more than 102.
