End of my rope

I'm struggling to find an answser for my symptoms...no one can difinitively come up with anything.  

I'm 50, female.  Had years of muscle pain, diarrhea/constipation, a large numb area from my L knee up to L thigh, frequent migraines, extreme fatigue...all beginning in the mid-1990's.

Within the past year, pain is constant, has now included extreme pain in the joints.  I'm also having a lot of muscle twitching in my arms and legs, this can go on most of the day, and into my evenings while in bed.  I sleep restlessly, altho a sleep study concluded nothing, and am usually in pain throughout the night.  My blood pressure (during the past 2 years) has dropped from a normal 120/80 down to 98/68, and sometimes lower.  My vision is bothersome, becoming blurry at times, eyes are watery or gritty a lot.  My ears have been ringing since 1992...and the ringing has increased dramatically.  The fatigue is incredible, and w/ the pain, nearly too much to bear. During the past month, I am having burning in my feet and legs.  One night in particular, 1 mo ago, I awoke to incredible burning in my entire L arm...it felt like it was on fire!  I also have neck pain, and for many years, an 'electrical' shock that goes up the back of my head when I turn my head to the L.  This has all led to a lot of anxiety and depression due to the lack of diagnosis, or where to turn for help.

I was initially diagnosed with FMS in 1997, but other doctors say No.  If it is No, then what is it?  No doctor I have seen (a lot) can come to a conclusion...one said "tennis elbow"!  I have tried Lyrica--it does not help.  I have tried Cymbalta--this causes severe nausea and vertigo.

Any suggestions would be appreciated, as to the direction to take.  Thank you.

I have just been diagnosed with " absence of septum pellucidum" (sp)
I have some similar ( although not all) symptoms to yours and it was initially thought to be MS - a MRI scan showed no sign of MS but this abnormality in my brain which is in the area where you hypothalamus and othe glands are ( these control various bodily functions) - this is a " birth defect" and has not cure for itself - but the symptoms can be treated -
just a thought as it is a bit of a rareity -
Hope you get some answers -
