Groin and Leg Numbness

I'm a 60 year old male. The past 2-3 weeks I have been having off and on numbness in my groin/rectum and either right or left leg. It does not go numb if I'm up walking around but only when sitting or laying in bed. I have a lot of arthritis and mild disc bulging. This did not start until I had a colonoscopy about a month ago. I also have a pain pump and CT Scans show that the caithier in my spine is in place and not broken. I've been going to a chiropractor the past week or so, about four visits and so far it has not helped. I also have a dull aching pain in my testicals when I urinate. My local doc did a rectal exam and it said the prostrate felt normal. Anyone have a clue as to what may be going on? It hit suddenly and I've not had any falls. Thanks, Bob
