I had an odd patient yesterday and it had me stumped. We were called to a clinic for a 39yo exhibiting signs of right sided weakness. I get there and start my assessment. He claimed it's been going on for about 3 days, same 'severity' all three days but finally decided to get it checked. Also states he has noticed some short term memory loss (not noticed by me as I gave him some words to remember, which he did better then I could have and I'm healthy!) No medical history aside from a broken arm when he was a teenager. Not on any medications, has not been out of the country recently, and hasn't gone swimming. No recent trauma / falls to speak of. No fatigue felt. Family history (aunt) of MS. I had him squeeze both my hands at once and the right side was noticeably weaker. I then had him push down / pull up on the feet, and again, right side was way weaker. Arm drift was negative (able to hold both arms out the same). I had him smile, show teeth, and stick out tongue and all was normal. Complains of no tingling, but slightly diminished sensation in the right extremities. The diminished feeling starts just below the clavicals which made me think that it probably wasn't CNS in origin, probably just PNS which means possibly peripheral neuroapthy? But caused by what? BGL of 117. Normal temp. Eyes PERL. Did a 12 lead and saw NSR with no ectopy. Anyone have anything like this? If I missed something that can help more, let me know and I'll see if I can get it up.
