I Had Unprotected Sex (march). Developed Back Pain During This

I had unprotected sex (march). Developed back pain during this time but took ibuprofen and was relieved. Later in the recent weeks(april), i had a sore throat that disappeared without any medication. After a month, i suddenly had this attack of stomach pain, fever and chills but then i slept it off(woke up d chills nd fever was over). In The next few days i developed a lower left adbominal pain that was persistent. The discomfort gradually subsided until around September when i woke up very thirsty and drank a lot of water through the day urinating about 20 times and also with sore throat and lot of phlegm. And since den have been urinating at an average of 15times a day
