Tomorrow, I will be 22 weeks. I definitely relate my symptoms to you. Life you said, some days, there's no pain. But other days, I find myself limping because of pain in one hip. I went to see my doctor today, and she suggested me to rest when the pain kicks in (if possible). Also, do Kegal exercise (sitting like doing Yoga which helps your ligaments to relax). She did mentioned if the pain become unbearable, i could try take acetaminophen. One more thing, when you sleep, try to have a pillow between your legs assuming you sleep in your side. Hope this helps. If you have any new ways of relieving your pain, let me know!
