Suggest Medication For Dizziness And Headache

Hii, I am 25 yrs old. My height is 5'3" and weight around 55kg. I am feeling dizzy from last three days. There is no headache now. I have felt so earlier too. But after some time It was OK. I have no habit of alchohol or anything like this. Even during my sleep, I feel like everything around is revoloving. I am also feeling pain in my thigh and below parts.
