Geek icon Kaley Cuoco, best known for her long-running role on CBS's The Big Bang Theory but also scheduled to play the title role in DC Universe's animated Harley Quinn series, took to Instagram today to share a number of brief videos detailing the homeopathic rehabilitation treatment that she has been subjecting her body to in the hopes of ridding herself of some persistent pain. The video (which can be a bit hard to watch at times) can be seen above. This is not the first time Cuoco has been frank with fans about her medical conditions; shortly after her marriage, she underwent a shoulder surgery and spoke frankly about that process on social media as well, as ET Online notes.
