Editing Trichinosis (section)

===Parenteral phase===
The severity of symptoms caused by larval migration from the intestines depends on the number of larvae produced. As the larvae migrate through tissue and vessels, the body's inflammatory response results in [[edema]], muscle pain, fever, and weakness. A classic sign of trichinosis is [[periorbital edema]], swelling around the eyes, which may be caused by [[vasculitis]]. [[Splinter hemorrhage]] in the nails is also a common symptom.<ref name=eight>John D. and William A. Petri. Markell and Voge's Medical Parasitology. 9th ed. Philadelphia: Saunders, 2006.</ref>

They may very rarely cause enough damage to produce serious neurological deficits (such as [[ataxia]] or [[respiratory paralysis]]) from worms entering the [[central nervous system]] (CNS), which is compromised by trichinosis in 10–24% of reported cases of [[cerebral venous sinus thrombosis]], a very rare form of stroke (three or four cases per million annual incidence in adults).<ref name=sixteen>{{cite journal |last1=Evans |first1=R.
