I am in my 5th week of proton therapy and have severe restriction particularly at night. I had some issues before the cancer diagnosis and took uroxatrol which helped. Immediately after my biopsy my urination problems worsened, couldn’t play a round of golf without running to the bathroom after 5 holes. One week after I started proton therapy the restriction began to get severe. So far the recommended treatment is to take 400 milligrams of ibuprofen once a day. It doesn’t help much. I hope to avoid a catheter and considering only doing 4 treatments a week instead of 5.
