Thanks for your queries. Yes, you can marry a normal lady. Polio
is a viral infection and will not affect your normal life now.
Regarding feeling of weakness, it is advised that you consult your doctor for finding a cause for it. If the muscles of your affected limbs
are wasted then you need to be on an extensive physiotherapy
programme to give them some strenght. The treating doctor along with a team of orthopaedic surgeon
and physiotherapist are the best persons to guide you after assessing.
With best wishes.
