loss of feeling in shin

[KristiAmbrosetti]

Hi, I am a very healthy 28 year-old female dancer/actor...I took a nap this afternoon, and when I woke up, I realized that I lost feeling in my entire shin area from the knee down to the ankle on my left leg.  I sometimes experience a part of my body being "asleep," but as soon as I move it around I feel pins and kneedles and it wakes up.  This time, it has now been four hours, and the feeling has not come completely back.  I am starting to get worried, and am not sure what is going on.  I am an athlete, do not smoke or do drugs, occassionally drink...work out four times per week and dance.  I don't know what is going on.  Can you please help me figure it out?  Should I be concerned and seek medical help?
I am able to walk, but still cannot completely feel my shin area...it is only on the top...the calf is fine and normal.  I can feel about 15% pain, but the rest of it, it numb.  
Thanks so much for your advice.  
Kristi

Hello Dr. Simran,

Thanks so much for the reply.  I don't have any spinal injuries at all.  It's really very strange.  The last thing that happened was a broken metatarsal on my left foot about 12 weeks ago from dancing.  Then the other day, after I woke up in the morning my entire left arm was asleep.  That was no problem getting the feeling back...very normal.  As of yesterday, all that happened was that I woke up from a very short nap and my left shin had no feeling.  To be specific, the inner part of my left ankle all the way up to midway up to my knee is numb.  I don't have a history of spinal damage or anything like that...I am a very healthy, active, athletic 28 year old woman.  I will try to get an appointment with my doctor on Monday.  Is that too much time going by, and will I lose feeling permanently if I don't get it checked out until then?
Thanks so much...

Hello Dear,
Was there any spine injury?You should consult a neurologist and get a MRI done to rule out any degenerative spine changes,neuropathy,nerve compression.You should do back extension exercises and yoga.
