I've been suffering since I was a child with migraine. As I grew so did my headaches. Eventually they became worse in my early 20's. By thirty I was a full blown cluster sufferer. The timing was impeccable and almost predictable. From my early 30's until about 40 I had them every 3 months for 2 weeks at a time or more. They would start somewhat manageable and then progress into the beast that we all know. Many sleepless nights and many hours of desperation. Those fights that go on so long until you're just exhausted from the battle. Sometimes it would clear and others you would be horrified to be awakened by another bout. I got to a point where I felt I couldn't take it anymore. Increases to meds, lifestyle changes, avoiding triggers it all seemed so endless. I was afraid it would never end.
Luckily my chronic status changed after 40. They became more spaced out, not as predictable and almost non existent. Then they would come back with a vengeance. The worst I've ever had. After a serious heart issue and resolution to that problem they disappeared yet again. This time for almost 5 years. They are back and progressing as they normally do. The pain threshold isn't as strong as it used to be but we are fighters. We wouldn't be here if we weren't. I won't quit until this demon is destroyed for good.
Hang in there. You're not alone. Everyone responds differently to different treatments and although we don't have a cure we can manage them better and support each other until no one ever has to suffer this pain again.
