I got to know a guy nicknamed "Happy Jack" some 20 years ago in Santo Domingo and he had a brown recluse bite at his ankle which never healed.
After some years and plenty of surgeries he finally died because of that spider bite.
He was bitten some where in DR but I don't remember where.
I am sure that some of the older DR1ers remember him.
Sorry to hear about your friend - I guess he was in the 10% according to this article (the one i provided the link for earlier in the thread done by a professor of entomology at NCU):
3- even if you have a recluse, bites from them are extremely rare, despite all the stories. Many of the really graphic nasty wounds you see on the internet as recluse bites can also be other conditions like necrotizing bacteria and pyoderma gangrenosum.
Ninety percent of brown recluse bites are not medically significant, heal very nicely often without medical. intervention and treatment for most brown recluse bites is simple first aid (RICE therapy ? Rest, Ice, Compression, Elevation). Many conditions are misdiagnosed as recluse bites when their cause is something else like infection, bad reaction to medication, diabetic ulcers, Lyme disease, or other underlying medical conditions.
