I do not have MS but have a close relative with it for decades, and a friend with it. MS can come and go. That is called relapsing remitting MS and is the most common form of MS. Progressive MS can also come and go in waves, but the general progression is down. It most commonly starts in women in their mid 20s to late 30s. It does happen in men, but it is less common. If you are in your 50s, you are past the time for MS to first show, though people can have it and be diagnosed with it at a later age than the 30s. Be aware that many things can mimic MS symptoms so it is best to check with your doctor to see what is happening with you. One of the first symptoms of MS can be depth perception problems though even new glasses can cause that. Please let us know what you are experiencing to cause you to think of MS.
