Hello ! You are probably suffering from a very critical illness. It is called "self over diagnosis ". The patients have usually minimal symptoms and present with all sorts of reports prescribed to them by various clinicians. Please stop reading on the internet and help yourself by seeing a good physiotherapist. Simple posture training will be good enough to relieve pain along with a bottle of hot water for fomentation. Uric acid causes pain and abnormally high levels are associated with symptoms but 5.8 is a very undernormal value.
