Dear Vicky Mahajan, hello
Before giving answer to your problem, I would like to know your age and your occupation i.e. your job profile.Whether your problem is only after dinner or anytime of the day/night?
I will advice you that please have a MRI
done of your lumbo-sacral area. Also have a Doppler Ultrasound
done of your legs. Also have your blood investigation done for:-
1. Complete Blood Count
3. Serum Calcium
4. Serum Electrolytes
5. Serum Folic Acid
and Vitamin B 12 assay
Also consult your Neurophysician for getting examined.
I hope this is helpful to you. Thanks.
