I don't think that what he has in mind for his
daughter.
Yes it is perfectly ok to ask. I was blessed in that it never slowed me down, much less stop me. Others are not so lucky. I know Lemon Balm tea is a sedative, it relaxes and helps you go to sleep.
I use Arnicare in pill and rub on cream or a gel for pain. I have a bum knee that the cartilage is gone, it gives me a great deal of pain. I take the remedies (pills) under the tongue and rub the cream on my knee. It is good for sore muscles and leg cramps too. The pain will stay away for
about 4 hours. I have even given Arnicare to my dogs for pain when they got bitten by copperhead snakes. I love this stuff.

A hot cup of Fresh grated ginger (available at grocery store) tea would also be soothing.
My husband uses Theraworx for leg and muscle cramps. He gets charley horse cramps that strike suddenly and are very painful. They are usually caused by depleted magnesium and potassium. So she might up her mineral intake with special attention to these two minerals. Theraworx is available at drug stores.
She may also have endometriosis.
Endometriosis is the development of uterine-lining tissue outside the uterus. Symptoms may include abdominal pain, heavy periods, and infertility. Treatment options include pain relievers, hormones, and surgery.
Try the herbal remedies first to see if they bring any relief. If not, she should see a doctor for a pelvic exam.
