[ 2 ] Sometimes, with a very flexible patient, the Thomas test will be normal despite a psoas dysfunction being present.
The pain can be so intense that it can be mistaken for a brain aneurysm, Cohen noted. "Cluster headaches usually last from 15 minutes to three hours and tend to occur in cycles lasting days or ...
