I saw a consultant 11 days ago who prescribed the drug indomethacin for my constant right-sided headache that I have had for the last nine weeks. I had an MRI scan showing nothing sinister. However, this drug is not working, and I don't know if I am expecting it to work too soon. I am in a lot of pain tonight and am seeing the consultant next Sunday. Should the drug be having an effect by now? As I am pushing my appointment forward, am I doing the right thing? I can't believe I am still in pain. The dosage is 50mg three times daily. Hoping you can advise me.
