I had that once and had great difficulty. Head vessels putting pressure on nerves. Then Lyrica. Still has side effects. I find a workout program that I do every other day is most helpful for relaxing and it seems to help reduce recurrences. I use “Grow Young Fitness”. Just google it. I like it because I do it quite easily at home at my convenience. I have to keep a schedule of every two days or three times a week. Nominal cost and once downloaded, you have it.
Very professional chair workout. Also helps with my knee issues.
