By chance have you tried a full spectrum CBD oil? I've been turning people over to this for years, for many ailments. One person I've helped actually HAD horrible migraines, took all sorts of stuff over the years from doctors and nothing really worked.. I got him to try some and 5 years later he has had No migraines and only at 3 drops in the morning, 3 drops at night... this should also help with pain, glocoma and shows promise with fibromyalgia.. it worth trying for sure, just find your dosage as 3 drops may not be what you need, maybe one drop, maybe 5, maybe 25 mgs.. just start low and work up. No sense in taking more than you need.. not that more will hurt or anything just wastes money is all. Message me if you want to know more about it or how dosing works etc, etc.. any questions I'm glad to help. Hope you have a wonderful day and hope this helps you, much love fren🥰
