I am a 35 year old male from India. My condition started with my left leg falling asleep around calf and foot. This started on the 04/24/08 the day after I learned the I will be layed off in a month. Mentioning this because it caused a little bit of stress. Then the tingling/crawling feeling started in my left forearm, face (particularly around upper lip/nostril area), and scalp. I saw my internist. He asked for some blood test and did some motor test. The motor tests were ok. The blood test showed low Vit D levels. He prescribed 50,000 IU capsule once a week for 8 weeks. As soon as I took the first dose that stopped my leg from falling asleep. Also when I wake up in the morning my legs do not have any numbness anymore. However, I still have tingling in upper lip/nostril area and scalp that comes an goes. It is not painful, feels like something is crawling on the skin. A few times a day, I also feel sharp pain in my fingers. Also some times, I feel pain jab simutaneosly in my pectoral muscles or ribs and legs (what's the correlation). Also lately, if I keep my hand on the key board for extended periods I feel slight muscle twitch in shoulder or any strained muscle. No muscle weakness, vision, or balance problems. Most consistent is tingling in scalp....very annoying. I am freaking out that it may be MS or some other neurological problem. The paresthesia is more present if I am under stress. I am thinking it may be a combination of anxiety and low Vitamin D. Can someone please inform me what kind of paresthesia is experienced in MS?
