Conversation: The conversation between human and AI assistant.
[|Human|] My son is 22 and just recently went back playing rugby after a year. He was diagnosed with grade 1 spondylolistheses at L5/SI secondary to bilateral pars defect. He is now complaining of pins and needles and weakness. He has gone to a college doctor and a physio today. Nobody seem to be to concerned. He does not live in the same city as me. I am an experienced nurse and I am quite concerned. I have told him to go straight to an emergency room if the pins and needles persist. I just want clarification on this.
[|AI|]  Hi there, if the tingling and weakness is in your sons legs I recommend that he goes to an emergency room without delay. A grade 1 spondylolisthesis is usually not very concerning, but if it is mobile (or unstable) and worsens with activity, it could be worse than a grade 1 currently and pinching the nerve roots that control his legs, bowels/bladder. I am extremely concerned about the weakness you state that he is having, and I would have him seek emergent medical attention without delay.
