Well what a fantastic site.    I had my radical prostatectomy done abut 2 months ago. Post op recovery went extremely well was up walking and showering the next day. Operation scar healed well, internal site a little soreness at first but after a a couple of weeks all good.

Now the bad news. 10 days or so after op date found it extremely difficult to walk without severe pain in my groin. Infact was using 2 walking sticks. Went back to surgeon who ordered an ultrasound. Result was all clear. Local Doc put me on Voltaren. 2 weeks further on now only on 1 walking stick but still a lot of pain so back to local Doc again. This time he ordered a Cat Scan. You guessed it, all clear but showed a slight build up of tissue though this is normal post op. Yeah "normal" alright why cant I walk properly Doc?? Well now no walking stick, have a bit of a wobble, still some great discomfort some days, pop a couple of Ibopufen  usually helps. The local Doc now wants me to hve a bone scan.I'm thinking about it.Well it is now 8 weeks out and things seem to be getting better slowly ( or is it just me getting used to the discomfort ) Other strange thing is I can only sleep on my back or stomach because if I lie on either side pelvic pain is too strong.

 

I had a somewhat similar episode to yours -- diagnosed as "spinal claudication". Started about two weeks after surgery, and symptoms were a serious ache in one leg that came on after about half-an-hour walking. Went away after resting the leg. Then about a further month later, the problem went away of its own accord and seven months later, it hasn't been back.

To rule out bone mets, I had an early PSA test -- you can't have bone mets with a PSA of 0, which mine was.

My uro explained that during surgery I would have been positioned in an unusual angle and that might have caused some nerve damage -- and surgery itself might have disrupted blood flow to some of the nerves.

Seems like your problem is on the mend too, and as the doc can't find anything wrong, I suggest give it more time. And exercise as much as you can -- keeping things moving should help -- provided your doctor is OK with that.

I know this may sound simple and the Dr. probably already checked, but have they checked you for a hernia, when they operate they arch the op table quite a bit, which is why some have back pain afterward.  I know in my case I had bilateral hernia repair in the 90s and a mesh was inserted, when they cut for the RP, the mesh moved and I know have that same hernia on the left side.

Just something to think about if they have not checked.
