Lower back (tailbone region) and hips (joint region ) hurt after periods of rest. Not muscle ache, feels like bone ache. I ve also have loss of energy and have beem getting sick when I eat a normal size meals ( have cuts meals to several very small meals a day) mri on lower back came back negative and blood work up showed no infection or cancer. Cholestrol, liver and kidneys were good also. The pain inlower back qnd hip joints has been going on for about 4 mths. I had a child 9 mths ago and did have an epidural that ddidn t go smoothly the first time so the dr had to re insert in a second spot above the first. The second and final spot had some skin nerve damage around the site and has since healed. The first problematic spot is were the pain is resonating from. I ve been to chiropractor and my family physician several times. I am 34 and have a history of camcer and RA very severely in my mothers side of the family.
It may be related to lumbar muscle strain during child birth. Minimal exercises may solve your problem. If pain is interacting with your daily activities, try NSAIDs.
