"I am still in chronic pain"

I was taken to A&E suffering from intense penile pain, I was admitted and next day had scan blood and urine tests but were clear. Since then pain has not ceased with pain also coming from up my backside, urology say nothing can be done as tests in January were clear, I am still in chronic pain 7 months later. I'm 60 years old. I understand there's a pandemic but its cruel to leave people in chronic pain, I feel they will pay no attention to this which is why I am considering taking it further. My treatment since January has been extremely poor. How can you leave people in such pain?
