My 10 month old son has had an unexplainable mild fever off on for months. The strange thing is, this fever only shows up when measured rectally. The 2nd strange thing is, it doesn't happen everyday. It's an off and on thing.
The fever is usually in the 100.4 - 101.5 range and not higher.
When I measure under the armpit, its normal, same with taking a measurement on his temple.
It is only when measured rectally is when it shows that he has a mild fever.
Any ideas what it could be? We did tests and nothing, the local Dr's are puzzled and really don't know what to do so that is why I am posting on webMD to share my story, hoping someone else can help!
