The symptoms as mentioned in your post can be attributed to nerve root compression
due to the disc prolapse
As the day progresses, the gap between the inter vertebral disc decreases(due to compression & dehydration)
Hence, the symptoms also increases.
Under such circumstances, it will be better to consult a Neurologist
& get a proper physical examination done.
So that appropriate management steps could be taken.
And MRI scan of the Lumbar spine
will be helpful in detecting the present status & progression of the prolapse.
Wishing you a Good Health. Let me know if I need to clarify further.
Thanks & take care.
