Hi Santos,
Because you have BHP Benign Prostatic Hyperplasia, you might have been prescribed medications for treatment that will cause swelling. For instance, Terazosin
is commonly prescribed and one of the listed side effects is swelling of the hands and feet.
Online sites are great for getting the information you need to ask the right questions of your doctor when you see him/her, but should never take the place of your doctor's solid medical advice and care.
I hope this helps. Please stay in touch and let us know how you are doing!Vicki M
