I've been suffering from coccydynia since April 2018. I've experienced a fall from the stairs. Xrays show no bone fracture or displacement. I'm 22 years old and have been on painkillers prescribed by orthopedics. Now the pain has stopped responding to otc analgesics. It's worse on sitting beyond 15 min. It radiates towards the left leg upto the big toe. I can't even lie down straight. There's no way it goes away. What should I do? I've tried physiotherapy, usg, infrared, TENS in the past but the pain has never disappeared completely. Do I need a nerve block or coccyx removal?
