Total newbie here, just had my first cluster headache 5 days ago. At least that's what my dr "thinks" it sounds like. I did get am MRI and it came back good with only sinusitis showing . I've had cold from hell at the exact same time...could there be any correlation between having a sinus infection and the onset of the cluster? Dr prescribed rizatriptan which didn't help at all. I feel like my headaches build until they get to a certain point and then explode and are pretty continuous. My left eye is droopy and watery, only had one very short aura at the onset of the first headache and am not sensitive to light. Right now Advil Dual or Acetaminophen helps the most but of course I have to take them about every 5 hours around the clock which puts me at over double the recommended daily dosage. I have to wonder if Covid has played a factor as I had a terrible bout close to a year ago and all sorts of weird things keep happening. I hope to get in to see my primary Monday but I feel lost and would love any advice offered. Thanks so much for any insight on this hellish thing!
