I was in Jamaica in 2010 at a all inclusive resort. I would assume that is where the Strongyloides came from, if that is indeed what this is. Aside from that, one of our animals had toxocara unknown to us. My wife actually tested positive to it, but her immune system fought it off and she is not in an active infection stage. Me on the other hand, I've been pumped full of both I.V. and oral steroids since 2008 on and off for weird problems that would come up with me. For example rashes, sores, etc..The I.V. steroids were given for cluster migraines I'd get day after day for weeks at a time. The steroids suppressed my immune system, which I feel allowed whatever is going on to go crazy and disseminate. I'cve had every blood test know to man come back negative. The area of Jamaica we were in also has been known to have the Filariasis Mosquitos. I was bit up like crazy while there for 2 weeks. I'm just getting worse all the time. My muscles are deteriorating at an alarming rate, I am almost to the point where I can't do any vigorous activity. I don't think I'll be here next Christmas. I think I'm losing this fight. So there ya go.
