Hi. Thanks for your query and an elucidate history.. The history of so many varied symptoms some related and some non-related with normal ultrasonography and some blood investigations are suggestive of you need to have: A detailed clinical and Physical examination by a a MD Physician. This is very important as there can be some syndromes mimicking these. You say the following history: Abdominal and back-pain- are indicative of retroperitoneal structure involvement; 2 late periods can be general illhealth and may not be a major issue unless accompanied by heavy bleeding or so. Achy sides and bruised coccyx can be due to fibro-myalgia associated with infection, stress and anxiety of not getting well. Same goes for the abs and both sides of abdomen. Skin can be rough due to deficiency of vitamins. Since you have not noted any sym,ptoms related to the intestinal problems like bloating , loose motions or so , all these problems can be related to the kidney infection which is not diagnosed and treated well. I would hence advise you the following: First of all get the urine and blood culture and sensitivity done to get an idea about the infecting organisms. Routine tests of blood, urine and stool. Intravenous pyelography and CT scan of the abdomen. Cysto-urethroscopy and Urologist s opinion. Once a proper diagnosis is made the treatment can be planned perfectly to get the results. This will be in the form of a long-term antibiotic, multivitamins and so on.
