Thank you for posting your query.
Your symptoms are new onset and hence require evaluation. It is possible that some new nerves or a part of spinal cord
has got compressed, resulting in leg weakness.
You should consult a neuro specialist and get an MRI
of spine done for appropriate diagnosis.
You would recover with early treatment and physiotherapy
Wishing you good health,
