Pain worsens when food is eaten
It could be as simple an explanation as muscle strain.
I am afraid to say that you might be suffering from kidney stones as urinating more than 4 times every night is not alt all normal. You should get yourself checked by a well-known doctor and then he might be able to guide you in the best manner possible.
I have pain In my side throbbing pain frequent urination also pain in my legs and feet
Well, no one can tell you from these symptoms about the exact problem until you go to doctor and take the tests. It can be gas when you have pain in your rib cage. You are not taking good amount of water, that's why your urine burns. Your stomach is also disturbed. I suggest you to consult the doctor as early as possible.
