The more information I read the more confusing this seems. OK so I read that PPMS usually starts with difficulty with mobility and in the late 30's or 40's. I have had this difficulty with walking for about 4 months now along with numbness, itching, pain, in arms and legs. I also believe that I have the MS hug going on as well. Last night it felt like I was having a heart attack caused a level 6-7 pain. I had the same thing 2 years ago and was put through all of the heart tests and the pain I was experiencing could not be explained as I am heart healthy according to docs. I am hoping for a break from these symptoms as RRMS would offer that in my future as opposed to the PPMS. So I guess what I am asking is has anyone out there reached almost 50 and had what now was probably RRMS symptoms but didn't initiate diagnosis until it turne into SPMS. I know that the MRI will show evidence as to which is which, but I am impatient and needing as much information as possible. Thank you in advance. T
