Dear Emma,
Beside the pain in the lower limb that you described as being sharp, do you have any sensory changes and if so where?
Is there any pins and needles tingling, numbness?
Is there any weakness or muscle wasting?
Did you try the neural tests for the lower limb? Nerve tension tests such as slump test, SLR?
Is there any loss of balance or coordination.
Can you walk normally on your tip toes or on you heels?
Please give me more details and what movements reproduce your pain.
Did you have any blood tests done recently? #
Please let us know so we can answer you back,
Nicoleta
