Respected sir, I am 35 years old, and I have pain problem in back and in knees. And one more thing is that I when I come from outstation then there is big pain in my head and then vomiting and after some time I get relief from my head pain if more then I go to doctor then they give me injection and I get relief, they tell me this is due to food those I have eat out of station. So please give me some solution. Thanks.
