My husband has had cyatica (sp?) pains for the past three days...lower back pain, radiating down the buttox to the lower leg. Tonight, it has exploded to such pain in the leg and swelling of the lower leg that he had to climb up the stair on all fours. He has taken two rounds of advil (200mg) for the past 8 hours, but doesn t seem to be improving. My question is should I take him to the emergency room for tests? Also, keep in perspective that he is approx. 350 pounds.
