What an awful last 5 months of daily migraines! Thanks to these daily migraines that started in February, where I had migraines for over 100 (!!!) excruciating consecutive days, I qualified through my insurance to get Botox. I probably would have been approved sooner, but I neurologist kept messing up the paperwork for my MRI and MRA (negative), and then messed up the Botox paperwork, too. This same neuro's office has a new neuro who is has been doing Botox for migraine for about 10 years.
I've had migraines for 20 or more years. Some times I'd only have 5-6 per month but twice I had them that lasted 6 weeks and were related to barometric pressure. My go-to med for the last 20 years has been sumatriptan (Imitrex). It usually works. I've tried rizatriptan and frovatriptan, but they don't do much of anything for my migraines.
Prior to February I was getting 4-9 migraines a month, which is pretty normal for me. I was diagnosed with menstrual migraines when I was 38 and was on lowestrin for 8 months. My menstrual migraines lessened after that. Through my 40's my migraines ranged from 4-15 per month, and twice I had them for over a month.
In February I lightly bumped the back of my head when I was crouched down doing something and went to stand up. I did not see stars or get a headache. I was totally fine. Two days later I bent down turned my head and suddenly started to get a weird migraine with aura. I was dizzy and nauseated. I suddenly became very very cold. I took my temperature. It was 96.1. I have never ever had a temperature drop when I've had a migraine. I immediately wondered about my pituitary gland and hypothalamus. The migraine raged on and lasted about 48 hours.
I have Hashimoto's and week later I tested all of my thyroid hormones. Well. My TSH (pituitary hormone) had dropped from 0.062 to <0.008. In other words, it was lower than the lab could test. My FT3 and FT4 were a little low, so I increased my T4 by 12.5 mcg. Then, my period was suddenly late. My normal monthly cycle averages 26 days. This one was suddenly 43. I decided to test my FSH (pituitary hormone - Follicle Stimulating Hormone) on the correct day of the month that this should be tested. Well! It was also much lower than it had been. It went from the previous 15.1, down to 5.2. I have now retested my thyroid hormones every month since this started and each time my TSH has been <0.008. That makes two pituitary hormones that are abnormally low. According to the neurologist, my pituitary gland and hypothalamus were normal on my scans.
So now I am wondering if these new migraines might be caused by a pituitary malfunction which has lead to my menstrual cycle being messed up and possible low hormones. My sudden menstrual problems could be strictly coincidental, but it's very strange how it coincided with head bump, the sudden daily migraines, suddenly undetectable TSH, and FSH decreasing by 2/3. I will be 52 in a couple of months. My period was very regular until it suddenly changed in February.
I saw a GYN last week. I asked her about hormones causing migraines. She said not possible. I said really? I'd just read many studies and article about this, plus I was diagnosed with menstrual migraines 14 years ago. I asked her about my weird FSH levels and how they dropped. She said they fluctuate all of the time and they didn't matter. I said well then why are they ever tested and how can you possibly ever make a diagnosis? She prescribed progesterone for me to take the last 15 days of my cycle for three straight months. Of course I went home to read more articles and studies about how migraines can be caused by low hormones, particularly progesterone.
I just saw a new doctor this week. He is and MD but is a functional medicine MD. He agrees and thinks that I might be on to something with my pituitary causing problems and also having low progesterone. He said that progesterone is neuroprotective. He recommended that I take daily progesterone for the next week until I see him next Friday. I admitted that I had already decided the day before to take progesterone. I took one 200 mg pill. My plan was to take it three days and stop, hoping that my late period would then start. I said that I felt more mentally clear and more energetic; could it work that quickly? He said yes. So I'm going to take it until I see him next week.
Now back to the Botox. I had it Tuesday. 200 units in three places on the front of my head, on the sides, occiput, upper trapezius where it meets the occiput, and both lateral sides of my trapezius. It is supposed to take up to two weeks to fully work. I think it is already working. I have barely had a headache, dizziness or nausea since the day after I got injected. Last week I had a throbbing migraine every day ranging from mild to almost severe. So far, so good four days after Botox injection.
I'd love to hear from other migraine sufferers. What, if anything has worked for you? If you've tried Botox, I'd love to hear how the experience was for you.
