Naturally, you should have an MRI. Everyone with CH-like symptoms gets, or should get, an MRI.
If you're not going to have an MRI, then you might as well treat it as CH and see what happens. I didn't want to say this in response to your first post for fear of scaring you, but for many people with CH, the first attacks and cycles can be more mild than what they experience later. So you need to learn about managing it. Sumatriptan tablets almost never help CH, because the attacks ramp up too fast for the tablets to take effect. If your attacks are predictable, you could try taking a tablet or two a couple of hours before you expect it, but you really want to try the nasal spray. 80 mg/day of verapamil is a very, very low dose, also not likely to have much effect. Maybe your doctor is proceeding cautiously, and will steadily increase that dose. It also takes a while for verapamil to get into your system, which is why some doctors give a steroid (prednisone) taper to reduce the pain while the verap has a chance to take effect. For your next attacks, try some of the things I listed, probably starting with the energy shot.
