Whether prostatitis needs detoxification depends on everyone's situation. People with damp-heat need to detoxify, but people without damp-heat don't, but from your query about the discomfort of swelling and pain, you also have prostatic hypertrophy, which is caused by swelling and stagnation of the prostate caused by damp-heat betting, so it is necessary to detoxify and dispel damp-heat, but the prostate belongs to the lower coke of people and can't excrete toxins downward, while people with damp-heat betting type are generally qi-deficient, so damp-heat can't be excreted normally through sweat glands and human urine. Therefore, it is necessary to replenish qi and promote damp heat, and then detoxification will have a good effect. I have walked the same way as you. I remember it clearly when I saw the doctor later. Traditional Chinese medicine (TCM) solves problems comprehensively, unlike western medicine, which treats the headache and the foot pain, but forgets the fundamental problem. We must make clear the treatment and solve it fundamentally, so as to solve it completely. I believe you can understand it and hope it will help you!
