I haven't seen all of Grace and Frankie, but the couple of episodes I have seen are pretty entertaining. In one episode, Grace (Jane Fonda) uses a vibrator that required so much effort she gives herself a case of carpel tunnel syndrome. Based on this experience, she collaborates with Frankie (Lily Tomlin) to design a vibrator that accommodates women with limited mobility, chronic pain, and rheumatoid arthritis.
Healthline wondered what real women with RA might have to say about a product like this - and I obligingly gave my two cents on the subject!!
