Hi:
I am a 28 year old male, non-smoker, occasional drinker. Excellent health until my symptoms flared up.
I started experiencing tingling and warm sensations throughout both legs about two months ago after performing some heavy leg presses at the gym without warming up (I hadn't worked out my legs in a long time). These symptoms soon turned to mild pain, greater in the left leg, and exacerbated by exercise. The leg pain is non specific and mostly dull in nature, punctuated by sharp, non-specific pain that moves throughout the leg (foot, calf, thigh). More recently, my calves are more affected. Also, I feel some pain around the knee area, and in the hip joint when I raise my leg by bringing my knee towards me. My balance is good.
On June 4, 2007, the right side of my face became numb with mild headaches, so I drove myself to the ER where a brain MRI was performed. The MRI was negative for signs of stroke, but did reveal a Chiari I malformation with a 5 mm. herniation with no syrinx. A cervical spine MRI accomplished on June 14, 2007 reconfirmed the Chiari I malformation and showed no syrinxes. However, the MRI did reveal that there is a C3-C4 3mm left paracentral disc protrusion which causes moderate left anterolateral effacement of the thecal sac, with mild central canal stenosis and mild left neural foraminal narrowing (no right neural foraminal narrowing is seen. Slight ventral compression of cervical cord).
Over the course of the last two months, my bilateral leg pain has slowly deteriorated and is my chief complaint, with mild headaches occurring on and off throughout the day. I had also experienced tingling in both hands, occasional pain in my arms and a feeling of elevated pressure in my head that leads to difficulty focusing when the headaches occur. These upper body symptoms have mostly resolved, but the leg symptoms remain. With regards to them, I've now perceived some weakness in my left leg along with the dull pain. I don't know if it is objective, clinical weakness, as I can still walk, run, and engage in sports. It is just that I notice that my left leg feels heavier (and in pain).
I saw a neurosurgeon last week, and he believes that the C3-C4 left spondylosis (which he feels is "recent" on MRI) is causing my headaches and leg symptoms (particulary on the left side), and suggested I use a over-the-door cervical traction unit, which I started using last night. The doctor did not believe that the Chiari Malformation was causing my symptoms, since my headaches were not exacerbated by exercise or the Valsalva maneuver. To confirm, he ordered a CINE-MRI flow study across the foramen magnum for CSF flow obstruction, as well as thoracic and lumbar MRI’s for syrinxes. The CINE-MRI showed no obstruction of CSF flow across the foramen magnum and the spine MRI's turned out negative for syrinx or spine problems. The neurosurgeon also performed a neurogical exam, which was normal.
I am seeing a neurologist Monday.
Are my symptoms indicative of ALS or something more treatable? What are your thoughts? I am concerned.
Thanks.
