<s>[INST] Hello. I am a 42 year old healthy male with no increased risk behaviors for cancer . I have trace hematuria (no stones...confirmed). It could be nothing I suppose, but I have a herniated L4 L5. Could this possibly cause this? Stiffness and pain experienced with the disk, as well as some flank pain and trouble (pain) flexing abs...particularly in the AM [/INST] Hello, Thanks for posting this question in HCM Let me clarify your problems in detail as follows::::::::::: First of all i would like to tell you that a given medical symptom can be due to various causes. For example back pain can be due to problem in spine or even can be due to problem in kidney, pancreas and so on. The other aspect in this regard is that a patient can have back pain due to two or more causes also. I mean one can have spine as well as kidney/pancreas/other problems together. Now let us see your problems.  I understand that you have disc related problem. This can explain the back pain.  Apart, you also have hematuria. This in turn can be due to infection in urinary tract, prostate,  kidney, stones and so on. This requires evaluation, clinical as well as investigations like CT scan which can define stone/other problem better than simple ultrasound Hematuria is not due to disc related problem Your disc related problems requires evaluation by a neurologist Please visit a center having these facilities and get evaluated at the earliest Hope this helps </s>
