I am 3 months pregnant. I have plantar fasciitis, Leg pain is so high now. My feet, calf muscles and knees are in so much pain. I am not able to sleep properly because of this pain. Not able to sit in a position continuously for 10 minutes, due to the pain. Usually Physiotherapy and stretches helps me. But now I am not able to do those stretching excercises now. Can I apply pain relief oil/gel in my knees and pain. Is it safe?
