Monster in my head

I'VE HAD THE MONSTER FOR ALMOST 20 YEARS. I'VE TRIED EVERY KIND OF MEDS THEY HAVE ON THE MARKET. THE THING THAT HELPS ME THE MOST IS O2 AND PREDISONE AND ALSO TORADOL SHOTS. I USE ICE PACKS ON MY NECK AND LEFT SIDE OF MY HEAD TO TRY AND FREEZE IT AWAY. THE COLD WORKS WELL ON ME . THIS CYCLE HAS LASTED 4 1/2 MONTHS. THEY USUALLY COME AT NIGHT WHEN I GO TO SLEEP AND LAST 30 MIN TO 4 TO 5 HOURS...... I SOMETIMES GO DAYS AT A TIME WITHOUT SLEEP WHICH IS HARD AND STILL TRY TO WORK TOO. PEOPLE TALK ABOUT MIGRAINES BEING SO BAD THEY ARE BUT I CAN HANDLE A MIGRAINE AND FUNCTION BUT A CLUSTER JUST ABOUT TAKES ME OUT. IN THE FIRST WEEK OR SO IT'S LOTS OF SHADOWS AND 1 TO 2 HITS A NIGHT. DURING THE PEAK OF THE CYCLE IT'S 4 TO 8 HITS A NIGHT DEPENDING ON IF I GO BACK TO SLEEP OR NOT. ANYONE WHO DOESN'T SUFFER FROM CLUSTERS TRULY WILL NEVER UNDERSTAND THE PAIN ASSOCIATED WITH THEM . LIKE I SAID BEFORE A MIGRAINE DOESN'T COMPARE I'VE HAD THEM BOTH .
