Constant warm water sensation on thighs and legs?

I've been having these "sensations" on both my legs,calfs, and thighs for about 3 weeks now. It feels like someone is pouring Luke warm water on them. They are not warm to the touch at all.It comes and goes during the afternoon. I've had a ct scan done, lumbar puncture and blood work done. The only thing abnormal was vitamin D. My Dr said normal is about a level of 32 and I have 14. He prescribed vitamin d of 50,000 units. Could the vitamin d deficiency be the cause of this? I'm afraid of something like multiple sclerosis. I'm a 19 year old Hispanics male if it matters. Please help thanks.
