You seem to be suffering from Lumbar spondylosis
with radiculapathy, probably due to strain on your back while lifting heavy weight.There is no reason to panic.Do not lift heavy weights or bend forwards. Try to take bed rest for a day or two. Do use firm mattress while sleeping.Take some muscle relaxants ans gabapentin/pregabalin
along with B12 supplements. take hot fomentation and undergo physiotherapy
in form of short wave diathermy and IFT.
Do be careful in future, and once when the pain settles do spinal flexion exercises to tone up spinal muscles.Do regular walk once you are pain free and maintain healthy posture. Do avoid lifting heavy weights, bending forwards and maintain the right posture to prevent back strain.
Do not indulge in alternative medicine like homeopathy
or ayurveda as this is degenerative disc disease
and the maximum benefit you can get is from regular exercise and priper maintenance of posture.
