Hi Jenn,
First of all, brisk reflexes are very common in people your age, especially on the anxiety-provoking doctor's exam table. I have them also.
Let's try looking at this from another angle, ok? Perhaps you really are having issues with your back, since that WAS why you were seeing a neuro-surgeon in the first place.
OK, so supposing it would be perfectly normal for a bfs-er to have brisk reflexes on both sides, now introduce an injury, a disc problem, a stenosis, or some other common problem with your back, which could actually lessen your reflexive response on one side. Considering it from THAT realm of possibility, it wouldn't be so abnormal for you to have asymmetry of your reflexes from right to left. Brisk on one side, decreased on another.
There have been others here who have had asymmetrical reflexes.
And, I'm not sure what he said about your Babinski reflex? It's usually either positive or negative? What did your toes do?
As for clonus, did your doctor actually TELL you that you have clonus, or are you self-diagnosing? If he didn't say you have it, then you don't have it. He already told you your reflexes are asymmetrical, what reason would he have not to tell you if you had clonus?
There are so many reasons why you could have this "abnormality." It could be an injury, it could be a peculiarity of your anatomy, it could be examiner error, it could be nothing. Jenn, with your cardiac history, you could have even had a very minor stroke that left you with no serious residual damage. This could have happened before you got the AICD placed.
I'm not trying to scare you here, only to tell you other things this could possibly be. I know of someone who is young, vital, and enjoying a very wonderful life, after having a rather serious stroke just a few years ago. She couldn't play her guitar for several months, but with rehab and recovery, she is now doing perfectly fine. I'm sure her reflexes are asymmetrical, too.
I've often said that if we test the population of the entire world with all the skills and technology we clinicians possess, we'd get 10 different results for 10 different people, none of which are perfectly "normal."
While it might not be prudent to ignore the fact that your reflexes are asymmetrical, you have been bumping along just fine with this, just as you were. MS has a relapsing remitting pattern, which you do not have.
I'm not sure if this helps you or not, but try not to worry until you have good reason to do so.
Hey, I had a patient in the hospital yesterday who was admitted with severe neck pain. Just woke up in the morning with it. Youch. She had regrettably been told by her doctor that it could be a metastatic bone lesion from a primary breast cancer she'd had years ago. She was very angry that the doctor had even suggested the possibility, and was, understandably fretting and freaking out.
I spoke with her for a very long time and told her exactly what I've told you. There are so many other perfectly viable reasons why she woke up with a sore neck. Heck, it happens to me almost once a week. I encouraged her not to ruminate on the fearful diagnosis until it was thrust upon her by a confirmed diagnostic test or told her by a qualified practitioner. I explained that some doctors have a need to present the worst case scenario.
She was discharged home this morning, feeling much better, and totally cancer free. Yet, to speak with her yesterday, she had herself practically dead and buried, all because some doctor had to go and open his pie-hole.
Blessings and hugs, my friend Jenn...
