Deletion of Treatments for chronic headaches

Comment: This exceedingly well-referenced and highly encyclopedic article handily meets . "pharmacological intricacies" are of great value to medical professionals and other readers with sufficient interest the subject matter; I have little patience for editors who seek to "dumb down" our science coverage through the exclusion of technical detail. The description of therapeutic methods in a neutral tone does not constitute instruction in violation of : only when an article abandons neutrality, and offers specific advice and suggestions does it run afoul of the policy. For instance, Treatments_for_chronic_headaches#Analgesic_and_abortive_medications is written in an acceptable tone, but the following rephrasing would be inconsistent with  (and would likely be construed as "medical advice" contrary to Wikipedia:Medical disclaimer):While you may be tempted to seek pain relief from analgesic medicines such as aspirin, acetaminophen, aspirin compounds, ibuprofen, and narcotics, and abortive medications such as ergotamine (Cafergot), triptans (Imitrex), and prednisone (Deltasone), abuse of analgesics and abortive medications can actually lead to an increase in your headaches.
