Hi elsie001
I'm really sorry that you are struggling with the migraines, they are beasts to deal with.
I can't advise re the hrt I'm afraid, it just created bigger migraine problems for me, though some women find that the correct balance does help.
I've tried many many things over the years and the only acute meds I've found to work are Frovatriptan, which has a long half life and therefore helps with menstrual migraine which are much more likely to rebound, and Diclofenac Sodium suppositories which allow you to bypass the stomach which is in stasis.
Avoid any opiate derived pain killers as they will aggravate the nausea and sickness when the stomach is in stasis. I have been prescribed them in the past and within minutes of taking them they would be swiftly expelled!!
I'm afraid the only way I find some escape is to take the meds, tuck myself away in a dark, quiet space with absolutely no stimulus and try to weather the storm. Fovatriptan should only be taken after the prodrome and aura have ended and the headache starts. It can take a while to work depending on whether the migraine sweeps in like a bat out of hell or it's a slow burner.
I wish you well elsie, they are pesky things!! x
