Hi @mykids, Welcome to Connect. I know it can be scary when you don't know what is causing your symtpoms and it's easy to think the worst case when do searching for answers. Since you mentioned you have high histamine levels, here is some information that might be helpful.

@bluecow, @tracyfurtiscaudle and @alleah may also have posted in other discussions about high histamine levels and may have some suggestions to share with you also.

Have you discussed the symptoms with your doctor or care team?
