pain and misery

So, for the past two days I have had to sit thru a workshop at work. It really was kind of interesting but not something I can implement in my job.  Yesterday I was noticing that I was becoming so stiff sitting in my chair.  I usually don't have that problem. My lower spine ached, my right hand had spasms and my leg was stiff and sore.  I started walking like Frankenstein but after walking for a little while it left me.  Seemed like I got my muscles stretched out.  Last night at home though I noticed my balance was extremely bad. I would turn around and almost fall down.  Then my right leg just stopped working.  So, today I have the Quasi Modo walk.  My muscles ache terribly in my right arm from the shoulder to the hand.  I cannot lift my right leg.  In order to get my shoes on this morning I had to pick my leg up and put it on the other knee in order to bring it up to the shoe.  I am also very tired. I have been tired all week.  Even last week I noticed I was getting more tired than normal.  Everyone at work is asking if it has something to do with the barometric change. We have a storm rolling in today.  Honestly, I do not know. I have wondered that myself. 
I have been slamming caffeine drinks because I can't keep my eyes open.  Yesterday in my workshop some of my coworkers were asking me about the testing and what all the docs have done.  These are people that I don't see on a daily basis and don't talk to a lot.   The presenter at the workshop has a master's in Nursing and was telling me some things to try. She recommended salmon oil to help repair the myelin sheath.  She also made sure I did not have any aspartame in my diet.  She was very kind.  Basically it is what it is.  Everyone this morning told me that I am such a "trooper" because I still manage to come to work and deal with this aillment.  I really don't have much choice do I?  
I am feeling down.  I do take my Effexor but that doesn't always keep the blues away.  I feel rather hopeless with this mystery ailment of mine.  More so than I think I have all year.  I suppose at some point the docs will find what is wrong with me. In the meantime I just have to live with my leg not working all the time.  I think the fatigue wears on me the most. The pain I can handle the dragging leg I can handle but being so tired all the time is hard.  I get grumpy and sad and find it so hard to cope.  I sleep like a rock so can't understand why I have this fatigue.  I have always been a tired person anyway. I have never in my life felt like I get enough sleep. However, I have never felt this tired.  It is miserable.
