Dear friend, welcome to HCM. If you say you have trouble initiating urination and also blood per urethra, you should take an urgent consultation of your urologist or a physician and look for retention. Please specify your age and sex to comment on possible causes. If it is painless bleed otherwise, a stone, infection, tumour are likely in the urinary tract. You will need a sonography of the KUB region. The discomfort seems to be due to urine retention due to some block there. Usually a prostate in a male. Please see your doctor and act accordingly. I think I could satisfy your query. Take care and keep me posted on your progress. Thanks !
