cluster headaches
"Prescribed 50mg indomethacin daily for Cluster Headaches along with 180mg Verapamil. While the Verapamil dosage seemed completely ineffective, the Indomethacin was almost completely successful at eliminating onset of headaches (nominally 4-5 times per day). Changed dosage to 25mg Indomethacin morning and evening, which was slightly less effective as the medication seemed to wear off in about 7-8 hrs."
