65yo Male W/ Chronic Pain, L Leg Radiculopathy, I Have

65yo male w/ chronic pain, L leg radiculopathy, I have severe calf muscle pain in either or both legs that presents mostly at night in bed and usually at least one other random time during the day presenting for last 2 weeks. No apparent physical reason. I have been riding an exercise bike for 20 minutes every other day. I receintly had a reaction to a statin drug but stopped taking the Zocor about 3 weeks ago. I had a DVT about 2 years ago following a lumbar fusion surgery but was cleared last month with an altrasound. I would appreciate your ideas
