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 orthopedic, 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.
