Do over the counter painkillers help at all with your cluster headaches?

I had a phone call with a doctor today and he doesn't believe that I have cluster headaches. Shocking. But he said that cluster headaches don't go away with over the counter medicines and now I'm doubting myself. I don't understand how my headaches fit perfectly the criteria of cluster headaches but because I take excedrin to deal with it, it doesn't match anymore? So now I'm doubting myself. Do you guys take any OTC drugs for cluster headaches?
