Hello Doctors, I am going with this problem since last 6 month feeling numbness, tingling on one side face, cheek sometimes other sides, it's for temporary.. but it's suddenly occur.. so I visited neurologist.. he suggested rejunex cd-3 tablet for one month.. he told due to anxiety.. it happens... but I can't see any improvement... sometimes neck pain also.. little bit...so please suggest me further... why numbness is their? is it serious? I'm worried..
