I have had hip pain, tibial pain and lower sacral pain...all increased with ambulation and activity. It does not feel like muscle but actually deeper, bone pain. It seems as though intensity increases when I go to bed at night then it almost pulsates with pain making for broken sleep patterns, Pain level consistently ranges from never less than 4 and often goes to 7 or 8, Little relief from Tylenol, Ibuprofen, or Naprosyn
