Fibromyalgia ? : 23y female with head fullness, stiff neck" & bilateral upper & lower extremity paresthesias, fasciculations & "muscle weakness" needs a general medical examination to rule out endocrine, autoimmune, & central nervous system disorders. Absent diagnostic findings, Fibromyalgia, hyperventilation & chronic anxiety need to be considered.
