@racox so sorry to hear about your husband's headaches. I had to look it up because I had never heard of it before. Although I usually get short lived headaches every day now I know it's not what your husband is suffering from. I imagine it can be quite frustrating to say the very least. I hope he finds relief. When I did a Bing search to find out what it was, I did see a Healthline article with self-help suggestions. It was called "18 Remedies to Get Rid of Headaches Naturally". I just went back and checked the suggestions and many seemed to make a lot of sense.
