I am a 50 yr old male with a history of right leg injury ( patellectomy, fractured femur- 30 yrs ago) recently reinjured my right leg... Got steroid shot in hip and knee. Now i have severe tingling, burning to my right thigh , groin down to my knee. What could be causing that burning and should i see a neurologist?
Burning and tingling sensation suggestive of neural involvement.  As you reinsured your leg it may be local neurological involvement, or it may be due to spinal involvement.  You should get radiograph of injury site to see the extant of involvement and MRI of spine to exclude the spinal cause. Local consultation better help you after examination which locate the level of involvement. Thanks
