Hi Charlene,   Thankyou for taking the time to answer my question.  His PPMS is in his lower extremities only... He's not fatigued!!     I question the diagnosis.......  His fall in 95 was a terrific blow to his body..  Landing on his feet...  He was in intensive care a day afterwards entering the hospital with multiple breaks and was in a life threatening situation.  Over the years due to the re-molding of his foot... As they said, they were working with what looked like a fried egg... having to take some hip bone to help sculp a new foot.  Over the years the wear and tear of his gait causing his spine to deterioate has caused this definite tilted walk.  The only thing I was suspicious of was the fact his leg went numb after 3 or 4 beers... I knew if he had a pinced nerve his leg would be numb all the time.  I've looked into it and it seems trauma doesn't cause MS... at least they seem to be on the wire about this... Either way... he has absolutely no other symptom of MS.... no fatigue, pain, etc.... only the numbness when he has a few drinks (social)... I'm questioning even though he's had all the tests.. gone to two specialists..  one is a MS specialist... does he really have MS.... His next appt. I'm going to look at the MRS scan and look for the dark mass they are talking about in the brain... From what I read... a dark mass without white spots is ppms.... with spots...rpms....  I was told his was completely dark...  I'm going to delve deeper into this and find out where in the brain this is seen and what that mass in that area effects...   I maybe in denile but better to go with my gut feeling and find out for sure than live with the suspicion he my not have ppms...   Once again.... thank-you for your response...
