Thank you. Since my post i've seen my family doctor who sent me to test my PSA levels as well a urinalysis. He's also referred me to a Urologist. I have not gotten my results yet,nor seen the urologist, however it seems we're on the same page for determining the problem.
Hi there!
Well, without a clinical examination it would be difficult to determine the cause of your symptoms. Possible causes to lower back pain could be related to spinal/ postural issues, degenerative disc disease, neuro-muscular issues, inflammations, degenerations, trauma/ injuries, referred pain from other regions etc. The discomfort reaching down to your legs could indicate a possible pressure on the nerve, though this is just a hypothesis and would require a physical examination and imaging studies to confirm the results.
For the issues with the urine, prostate enlargement could present similarly, though other possibilities such as neuro-muscular issues, side effects of a few medications etc; may need to be considered as well. Also, benign enlargements of the prostate may be associated with back discomfort; while in somebody who is older one might have a reason to rule out malignant secondaries to the spine.
In the current situation I would suggest consulting a urologist for a start and if advisable you might see an orthopedician for the back pain; or alternatively one might consider beginning with a primary care physician.
Hope this helps.
Take care!
