Dear doctor,I have a slight tingling throughout my right leg and there is an area of skin 4 by 5 inches or so, that feels senseless, at the top of my thigh on the back (top of hamstring). There is no pain or functional impairment.I did come back from a long airplane flight 3 days ago, I did wear pressure-socks up to the knee. Also, i did do some physical labor 2 weeks ago that still bothers my lower back a bit every now and then, like a brief pain shoots through.Not sure if these details are possibly related.What do you advise? Thank you in advance,Chris
Hi, Chris,welcome to Chat Doctor forum.  You have tingling in the right thigh, after a long air journey. You had hard work, 2 weeks ago, and the back is still paining.  Hi it appears that you have lumbar spondylosis, due to long journey there was a pressure on the sensory nerves coming out from the spinal cord.  You may need to have M.R.I. of the spine for diagnosis, so I advise you to consult an orthopedic surgeon for diagnosis and treatment.  Wishing for a quick and complete recovery. Thank you.
