Hello and Welcome to HCM,
Thanks for writing to us.
The symptoms that you are having are likely to be due to a nerve root compression at the level of lumbar spine(L5). You need to get an MRI scan of the area done and consult a orthopaedician for proper diagnosis and treatment.
Hope this helps you.
Wishing you good health...
Regards.
