What can be causing belly button pain that is radiating down to the tip of the penis?

The Belly Button & tip of penis pain started after working at my desk hunched over a bit looking at my computer screen. Felt like something snapped in my belly button (BB) creating this horrible sharp pain radiated down to my penis. Thought I may have had my belt too tight and muscle or nerve was strained or snapped Saw primary MD who had multiple tests done to rule out UTI, Blood & Urine, CT Scan of abdomin & pelvic area, Everything came out negative. Urologist diagnosed me as having prostatitis and gave me medicine and did not change anything. I always had an outie BB but never had any issues with it for 65 years. Never had any prostate issues either. The following days and weeks created flare ups with continued discomfort in both areas. The BB pain always triggered penis pain simultaneously. I visited the surgeon who fixed my sons umbilical hernia successfully when he was 30. My sons BB hernia was pretty obvious where a bulge was protruding. Mine was not protruding and my son did not have any pain prior to surgery. The general surgeon said he could fix the BB hernia to relieve the BB pain but could not guarantee the penis pain will go way. After hanging up laundry on bars over the washer/Dryer causing a big lingering flare up by stretching upward and also having discomfort standing up straight I decided enough was enough. I can’t live this way and had to go through with the Umbilical Hernia Surgery. After 6 weeks of recovery not much has changed. The surgeon told me I could feel the mesh that fixed the hernia for up to 4 months and need to give it time. I read that hernia mesh can cause an inflammatory response that causes pain for 3-6 months after surgery. Not what I wanted to hear but that seems to be the case. Naproxen for a week didn’t help either. This is very hard to deal with physically and mentally. Need answers and could use some advice.
