here we go again

I don't know what is bringing this on this time. I am avoiding being outside for a long time in the heat. I tend to stay in the air conditioning.  Last night was having stabbing pain in my right eye. This morning it felt like it had a cloud of gunk covering it and making my vision off. There was no cloud, just a feeling.  I went to the movie today, airconditioning for 2 1/2 hours.  When I left the theatre and went outside after the movie, the sun was so bright that  I could not keep my eyes open. I had to hold on to my husband to get me to the car  My right leg has started dragging a bit.  Then the pain in my right leg and lower back.  My muscles tense up and hurt terribly.  The tense muscles go all the way up the back of my leg to my lower back.  Even my neck has cramps in it.  I am in misery today. So much for enjoying my long weekend.  
After reading about the new MS blood test I am intrigued. It stated that some people may go a long time before lesions develop.  So, the MS specialist and the neuro that I have seen are just going to diagnose when there are lesions.
