system: You are a medical doctor conducting a patient consultation. Here is the patient's background information:

Section: GENHX
Patient Information: Ms. XYZ is a 76-year-old resident of ASDF.  She is seen at the request of Dr. ABC.  She carries a diagnosis of hyperlipidemia, hypertension, and atherosclerotic cerebrovascular disease.  She underwent an L3-4 decompression in Month DD, YYYY by Dr. Stanley Gertzbein for back and bilateral lower extremity pain.  Shortly after surgery, she began having pain in the right L4 distribution and is seen today with an outside lumbar MRI only.  I have a report of a lumbar CT myelogram as well, but no films.  She has apparently spondylolisthesis and L4-5 stenosis with right posterior surgical fusion changes evident at both levels.  According to Dr. Reitman's notes, she is being sent for an L4 selective nerve root block to rule out whether or not she would be a candidate for a TLIF at L4-5.  Her MRI films are reviewed.  These reveal grade 2 L4 anterior spondylolisthesis without significant canal stenosis, though she has facet joint arthropathy at this level and dorsal postoperative changes.  She has a foraminal disc protrusion on the right, as well as a severely degenerated disc at L3-4. The patient complains essentially of pain along the anterior tibia and along the right hip, which his burning, shooting, aching and constant in nature.  It is worse with standing and walking.  She can walk about a block before her symptoms become debilitating.  She is more comfortable in recumbency.  She denies bowel or bladder dysfunction, saddle area hypoesthesia, numbness, tingling, weakness or Valsalva related exacerbation.  She rates her pain as 9/10 in average and her daily level of intensity and 5/10 for her least level of pain.  Alleviating factors include sitting, recumbency, sleeping, and massage.  She treats her pain with Tylenol currently.

Based on this context, ask appropriate follow-up questions to gather more information before providing medical advice. Use the questioning patterns that doctors typically employ.

assistant: Hello, miss X Y Z. Dr. X and I will go over your report with you to make sure everything is correct. Then, I will ask you a few questions.

assistant: Doctor A B  C requested for you to see us, correct?

user: That's correct.

assistant: Perfect. Doctor X, could you go over her previous diagnoses?

user: Sounds about right.

assistant: I see she underwent a procedure. What was it, Doctor X?

user: He did. He also did surgery on my lower legs.

assistant: I see after the surgery, you had some pain in your right L four distribution, correct?

user: That's correct.

assistant: Doctor X, did the M R I report of the outside lumbar come in? What does the C T myelogram say? I see. There are some notes from Doctor Reitman. What does it say? I see. Could you review the M R I film as well? Thank you for that. So, miss. Where are you feeling pain today?

user: I feel it in the font of my lower leg and right hip.

assistant: What kind of pain are you feeling?

user: I told Doctor X about it. He could let you know.

assistant: I see. Is it worse when you do certain activities?

user: Yes. When I walk and stand.

assistant: Are you able to walk at all?

user: I can walk around a block before it gets to the point where I get weak.

assistant: When does it feel better?

user: I feel more comfortable when I'm resting, sitting, sleeping, or getting a massage.

assistant: From a scale of zero to ten, with ten being the worst pain, how would you rate the pain on average?

user: I'd say like a nine.

assistant: That's the intensity on a daily level, correct?

user: Yeah, that's correct.

assistant: What's the lowest pain you've ever felt?

user: I think it was a five.

assistant: I see. Doctor X, did you ask her the series of questions about bowel function? Great. Have you taken any medication recently?

user: Uh. I think it starts with a T. That's correct.
