Good Day Doctor, I Was Diagnosed Of HBV And 5

Good day doctor, I was diagnosed of HBV and 5 years after I started taking the drugs for it but before then I was fine but as I continued taking the drugs I developed pyelonephritis and has taken several antibiotics like ciprofloxin and levofloxin on several occasions as prescribed by the doctor here , I now get very weak very often and stiff neck and pains by the right side of my rib cage and below my back and sometimes the pains flashes at the left rib cage and goes out , and I always experience heavy gas in my stomach and bloating when ever I wake up and often problem with food digestion. Please help me out , all the tests I did showed nothing apart from the pyelonephritis indicated by the ct scan .
