Tingling and moderate pain in left thighI hurt my back a couple months ago by picking up something that was too heavy. The pain when I lean over finally went away but now I am getting a tingling sensation and dull pain in my left thigh. I also feel like something is on my knee as well like a hair. This has been going on for about 4 days now. I am 30 years old and I have had two kids but I am in very good shape and active. I run a few miles every week and still play softball. Its the weirdest feeling in the thigh. It starts at my bikini line and goes to my knee. It almost feels like a burning sensation....?
Your mode of injury and the nature of your pain ( radiating , burning )  gives some insight into a possible disc/ nerve compression issue . I would suggest you seek medical examination from an orthopaedic , who might also want to investigate in the form of an MRI and perhaps recommend  physiotherapy , which is generally done  in such cases.  In spite of you being in good shape , particular attention may also be required with your routine  postural habits , the type of exercises you do and specifically the core muscle  strength, all of which the physiotherapist will assess and guide likewise. Even if your pain subsides , with rest and medicines, issues pertaining to muscle strength and ergonomics will need to be sorted out to prevent future similar occurrences.
