Hi Katherine,
Thank you for your question. I'm sorry to hear your migraine attacks are becoming more frequent - that's frustrating.
I've not tried the PT you mentioned above. Hopefully others will be along shortly to share their experiences with you.
I did want to mention there are over 100 medications that can be used to treat migraine, not including supplements, so don't lose hope! You can read more about these medication in this article; https://migraine.com/blog/migraine-management-essential-4-preventive-treatment/.
Medication overuse headache or moh, formerly called rebound, can be a real problem if we take migraine medications (sumatriptan) and/or pain relievers, whether they are over-the-counter and/or prescription, more than two to three days a week. If we are in an moh cycle our migraine attacks will be more difficult to treat and we can end up in a daily cycle of pain that too is hard to break. This article has more information on how to treat migraine and not overuse medications; https://migraine.com/blog/help-how-can-i-not-overuse-migraine-medications/.
I hope that helps,
Nancy
