Topical Coconut Oil Allergy?

I need any info i can possibly get! I have known of coconut allergy for a few years now but i have avoided ingesting it. For the past month i have been having severe itching all over my body aswell as stomach problems. When the itching began i started looking for coconut in my bath products etc, and one after another had it in it. I have elimated everything i found however I am still itching like crazy and slowly going nuts. I don't understand how this only began recently when it seems that coconut oil is such a widely used product. Could it be some other medical condition triggering the side effects?
