I was diagnosed with PPMS right from the start of my official diagnosis in 2006, they played around for 3 years prior to that assigning labels to my illness.
I lost the ability to walk normally fairly quickly, with in a year? My legs, especially the knees always felt weak. I had random patches of numbness on my thighs, I dropped things, dizziness, vertigo, motion sickness. My stomach, bladder and bowels rarely feel quite right.
Things for me have just progressed, I didn`t buy into any of the treatment plans to try and slow the progression, I felt the risks far outweighed any possible gain.
I am in the process of losing the use of my left arm, my feet always seem to feel numb, I get terrible legs cramps, the MS hug occasionaly. The heat affects me badly, I feel fatigued constantly.
No depression and few if any cognitive issues, I diagnosed myself a year and a half in, and spent another year and a half playing around with doctors that had cognitive issues until I went to a specialist that ordered the proper testing to confirm my diagnosis.
LOL, I only act crazy, it keeps people that only think they are normal at a distance. I guess it is one of the benefits of a late onset? I never figured I would make it out of this life alive anyway.
I am more or less stuck around the home and yard 24/7, but I have done enough in life to be content with that reality.

Oh no! wer`re all going to die! LOL
I do feel sorry for the younger folks that never get the chances I had. I used and misused a lot of them.
