Hi thanks for your query and welcome to lybrate. I am Dr. Akshay from fortis hospital, new delhi.
See, if you have numbness
in one half of the body, it is important to clinically examine you and focus has to be on cervical spine and brain region.
Since this is a slightly sensitive issue, I will advise you to get in touch of a neurophysician and get a detailed evaluation done for yourself. Do not hesitate to contact me if you need any further assistance.
