Ok, I am not sure what happened, but my post didn't appear, so I am reposting.
I was reading this article, "Worms, parasites drain US poor, expert says"

And then came upon the article that talked about a rare case of a joint problem arising due to a parasitic worm invasion.
The medical article is called "Strongyloides Stercoralis Infection Presenting With Severe Malabsorption And Arthritis In An Immune Competent Host"

Some quote - "helminths such as S. stercoralis are more frequently associated with musculoskeletal involvement. This may be due to their greater antigen complexity and invasiveness [ 20 ]. The mechanism underlying the arthritis associated with S. stercoralis infection in our patient is unclear. One possibility suggested by her MRI scan is direct invasion of her joints. This is a rare event. Indeed, only one case of S. stercoralis associated arthritis reported actual presence of the organism in the joint [ 12 ]
