Low back pain is usually not caused by prostate enlargement. Low back pain is mainly caused by lumbar spine fracture, herniated disc and other reasons. Prostatic hyperplasia is mainly characterized by frequent urination, urgency, difficulty in urination, and increased nocturia. The main causes of prostate enlargement include aging and functioning testicles. One of the most prominent early symptoms of prostate enlargement is frequent urination, which is more pronounced at night. As the disease progresses, there is an increase in the amount of residual urine and the frequency of urination gradually increases. In the later stages, the most important symptom is difficulty in urination, and there will be delayed urination and urinary retention. The treatment mainly includes medication, such as terazosin, tamsulosin, finasteride and so on. It also includes surgical treatment, the most important surgery is transurethral resection of the prostate. All the above medications need to pay attention to the side effects and adverse reactions of the medications, please use the above medications under the guidance of your doctor. While the causes of back pain include lumbar muscle strain and ligament strain, lumbar disc herniation, lumbar trauma, etc., it usually has little to do with prostate enlargement. Once you experience back pain or prostate enlargement, you should go to the hospital and seek medical advice under the guidance of your doctor.
