Try taking magnesium. I had that problem and after taking magnesium, the problem is much improved. It takes about a month. I had read on the internet that magnesium is all about nerves and muscles. Most women are deficient in magnesium. I can tell if I forget to take it for a few days. I get it at Walmart. I use Spring Valley. It works where another brand that Walmart carries does not. It also helps leg cramps at night.
good luck. My daughter had the surgery and thinks that it is wonderful.
