Jerry,Hi my husband has ppms and it started in 2000 when a tractor rolled over on him while bailing hay,he was life flighted and in a coma with swelling of the brain, He woke up after 3 days and threw a fit and wanted to come home, he still had a fever of 103 degrees, David (my husband) is 6ft.4 and was strong always farming and hunting, I've never met a stronger man. After several months he started complaining of double vision,took him to more doctors and they said he needed a sinus cavity operation, so he did it and it did help his vision, then when he was out of state he had his first relapse and couldn't walk and ran a bunch of tests and said he might have ms when I got him home I nursed him back to health only for more relapses, while on steroids I became pregnet with our son at 40  years old. David was having more lesions on the brain and was put on Rebif, he took it for a while then stopped without my knowing, David is in a nursing home now and has been there for over 3yrs. he had ended up in the hospital again while out of town in2005 and had anmonia and almost died, was on life support for 8days, its been a long road just to get him where he is now.David was on a tube feeding for a year and now eating on his own, but he has atrophy in his hands and feet and has to have someone feed him.I believe his ms made him asperate and that is how he got anmonia. His doctor says there is nothing for ppms but I won't give up hope.David is not competent and thinks he walks, not sure if it is due to lack of oxygen from anmonia.So anyone who has this diseise, please pay attention to your symptoms and be careful about swallowing. David's doctor has him on Rebif again to keep it from progressing but I've read thatRebif is used for secondary and not primary. Keep up on all the new info and keep moving and stay stress free, that is what will set it off. Thanks for the ear, Thouhtaboutit!
