I'm a 26 year old male who has gotten cluster headaches since 2015. When they started, they would usually occur between September and November, occur at the same time each day, and last only 30-45 minutes. I was able to deal with that through OTC pain medications. This past Autumn, the Sept-Nov cycle came and went without a single headache. I thought that I was free. Come April 2021, they returned with a ravaging vengeance. They are now unpredictable, occurring any time of the day, for now periods up to three or four hours, and with intensity I hadn't felt before to the point I cannot function. If this continues, I don't know how I will be able to continue studying and working. I don't know where else to turn, so I am reaching out to strangers on the internet for any advice you may be able to give. Much Thanks!
