I am having issues with Constant Urinating

I am hoping to find the attention of a doctor here please. I don't have the means to go to the hospital now hence why I am here. I believe I caught an infection last year. I urinate a lot, like a lot! I urinate like five times in less than an hour. And when I am done I feel like there's more remaining but I can't get it out while I still feel a weight in my bladder. I get some pains while peeing also. I took Ciprotab and it didn't work. During Ramadan I called a distant relative who is a doctor and described my ailment to him. he prescribed Augmentin, Flucamed and another drug that I can't remember the name, but that specific last one has some side effect such as feeling nauseous and dizzy. Anways, i finished my dosage and I felt okay for a day. But after that the constant urinating continued without the pains. I am so fed up of it. It is getting in my way as a student. I can't go out to read at night because I'll keep going back to the hostel to pee. I can't stay still in classes, it's really affecting. I just want to know if there's another drug that will help my situation.
