I have been on strong painkillers for along time (15 years) and now i am facing tests for kidney disease and i am so worried. I have been told i have a heart murmur now and blood and protein in my urine. I have been feeling generally unwell for a while different to the norm with the health issues i have . I have pain in the region of my kidneys , a strange pressure pain in my back in the morning which they say could be fluid on my lungs due to kidneys not working properly. Plus i am more confused than normal . Whats happening to me ?
