I've had migraines for years, not cluster headaches, but my experience has been that a neurologist who specializes in headaches is best for diagnosing and treating them. If your doctor is not a headache specialist, and you find that his recommended treatment is not working, then you should consider seeing someone else.
Feedback to your doctor is also important -- if the Imitrex is not working, let him know. There are other meds out there which might be more helpful, or you might just need a stronger dosage.
Also, do research on your own to see if lifestyle changes might be helpful. When my migraines were at their worst, it was very important to keep to a regular schedule for eating and sleeping. Stress management can also be very important (though I never did figure out how to do that). Grinding my teeth contributed to the problem, and I also found that wearing heavy necklaces bothered me. Other people find that certain foods can be migraine triggers -- I don't know if cluster headaches also can react to foods, but it's worth finding out.
Good luck!!
