Hello - I am a 40 year old male who spends most of my work time sitting in an office. About 1 1/2 months ago I came to the office and noticed that I had muscle twitching in both calves and my mind was in a fog. As a side note: I had been suffering from diarrhea off on on for about 6 months. I also drank a lot of coffee throughout the day while at work. I have eliminated the coffee completely since the episode and tried to stay hydrated. My muscle twitching for the most part has eliminated. I went to my GP about two (2) weeks later. I stated to him that the calve muscle twitches had subsided but that I had periodic numbness in my fingertips and toes (usually at night) along with some flash heat sensations (last a couple of seconds) on my feet. He ran blood test and all the test came back fine. The blood test checked for diabetes, Thyroid issues or B12 deficiency - no apparent problems. They also did a EEG on my foot/leg and lower back and no nerve damage. He suggested to stop with the coffee and get some exercise (I am about 30 lbs overweight). With wanting to get a second opinion I went to a local neurologist (obviously concerned about a condition of MS or ALS) and she did a visual exam (no swelling) ran some more blood test along with an xray of my back (to see if there is a pinched nerve) and everything came back fine except for a Vitamin D deficiency (I tested at a 15 and apparently I should have been in the 30 s) She stated that in her opinion that I did not have MS or ALS and we talked about exercise and eating a heather diet (in which I agree). My GP stated that I should take over the counter Vitamin D at 2000 icu. Since the visit I have been taking a Multivitamin, Vitamin D, Vitamin B6. The problem is that I still have tingling in my toes along the heat sensation in a portion of my left calf and feet. I am not sure where I should go next. There however has not been any pain associated with the symptoms. Thanks in advance for any advice.
