I'm really hoping you wonderful people can offer me some advice or comments while I wait for more tests to rule out (or in) MS. Of course I'm very upset about my neurologist's suggestion of MS, but my biggest concern is that it's something else that is not being properly treated. I'll start with my backstory and symptoms and please forgive the length of this post....
First, I must point out that I'm a scientist and by nature analyze everything! This turns out to be very very challenging in a situation like this because I research every symptom and then research every differential Dx for that symptom then research the common symptoms that I don't have to try to rule things out....all the while flooding my tired brain with way too much info and only more questions. So I figured that asking the people who really know the disease was my best resource.
I am a 36 yo previously active and healthy female
I've had a "bad back" for as long as I can remember. Always seems to be muscular but is a recurring problem.
I have moderate iron deficiency anemia with an unknown cause. Ferritin levels are extremely low.
All other common blood work normal ie CBC (aside from reds, Hb and Htc), CMP, TSH
I've been told by drs that I have superficial ulnar nerves which results in pain at elbows and tingling pinky and ring fingers usually after sitting at my computer for an extended time.
I do not recall any other past neuro symptoms although I can't be sure that they weren't there and dismissed. I did have one small spot on my left forearm that was very sensitive and painful to the touch for a week or so a while back and was similar to the description of shingles pain.
In March of this year I was involved in a sporting event that required a lot of heavy lifting.
In April I began having daily headaches and a general feeling of malaise which was accompanied by a positive flu test. Other blood work normal aside from anemia.
Headaches continued through the month of May. I was miserable everyday and started having additional neuro symptoms such as some intermitting pain and tingling in arms and legs (both bilateral), inability to concentrate (I attributed that to the headaches), some clumsiness with my hands, foggyness and severe lower back pain and neck pain.
PCP ordered a brain MRI for headaches which showed multiple small periventricular foci of hyper intensity, none of which enhanced with contrast.
I was referred to a neurologist
I believe my neuro exam was rather normal. I have no loss of balance or coordination and easily performed all the tasks that were asked of me. The Dr. even commented on how fast I was walking on my heels and how strong my arms and legs were. At appointment I had numbness and tingling in hands, legs, and feet plus one constant spot of tingling in the middle of my back, just to the right of my spine. He ordered the standard MS blood work up to rule out all the mimics. All normal.
I have no noticeable visual changes. VEP was ordered and came back abnormal with a left eye delay. Although I know this is a sensitive test, I'm not 100% convinced of the results as the EEG tech never instructed me on how to take the test so therefore my eyes were wondering the entire time and not focusing on the center of the pattern. So while this has an abnormal result, I don't put much stock in it in my case.
At this point I started developing additional symptoms. Tingling in fingers turned into pain in arms, hands, and wrists (bilateral). My fingers began to lock up especially in the morning and evenings. The locking was not painful just seemed to be a slipping of the tendon where I was able to open my hands but not with a fluid motion. After research, I could best explain it as a possible inflammation of the tendon sheath which was preventing the tendon from moving freely. My toes and knees seem to feel similar but not as drastic. EMG of upper extremities was ordered and was normal. Blood tests for Sed Rate, ANA, CRP, RA all normal.
MRI of spine (cervical, thoracic, and lumbar) was ordered. No lesions were found. It did show a herniated cervical disc with mild stenosis and a small herniated lumbar disc. My neuro says that he believes these two herniations would cause pain but not the symptoms in the extremities. EMG of lower was ordered and scheduled for tomorrow. I have a lumbar puncture scheduled for next week.
I had an appt with PCP who commented that he is not convinced that it's MS. Says something is definitely wrong but wouldn't say MS. Tells me that all of my blood work (and I've had a lot) is good. I even have good levels of Vit D which is very rare in the North East where I live. I look healthy and can move and function well (aside from my low back pain). Also went on to scare me about the current MS drugs and why I don't want to have to take them.
Currently my symptoms are muscle tightness and pain in hands, arms, shoulders, legs, and feet. Fingers and toes are still locking. Headaches have been gone since June. Tingling and numbness in legs and feet are mostly gone but will come and go based on my level of activity for the day. Almost always bilateral and mostly relieved by resting. The tingling in my back is still there and constant although it is relieved by laying down as well. I've started having muscle twitching in my legs and occasionally in my hands and rarely in my face.
So here are my questions. I really hope someone can help me.
Abnormal brain MRI, abnormal VEP, and multiple neuro symptoms all suggestive of MS.
But, if this was an MS flare, and if not my first then most definitely the most significant one I've had, why would none of the small foci enhance on MRI?
I also find it strange that all of my extremity symptoms occur bilaterally and are mostly relieved by rest. If there are no lesions in my spine and EMGs are normal, would a small spot in my brain cause so much damage bilaterally?
Is it common to have symptoms of just parasthesia without other neuro symptoms that affect vision, balance, coordination, speech, etc?
Any ideas on my fingers locking? I can't figure out how to attribute it to MS. My hands are strong and dexterous so I don't think it's muscle related. It really feels like inflammation but all of the inflammatory markers that were tested came back normal.
Any opinions on how possible it is that:
Most of my symptoms are simply caused by my bad back,
The VEP results were incorrect,
AND the spots on the brain MRI are due to something other than demyelination?
I guess I'm still holding out hope that it's a series of unrelated coincidences.
