Are you taking Flomax for prostate issues? Flomax works by relaxing the muscles in the bladder and prostate, which leads to improved flow of urine and fewer symptoms of BPH. It indeed can have side effects like you describe. https://www.healthline.com/health/enlarged-prostate/flomax-side-effects#side-effects It's a relatively low percentage of patients, less than 4% that have these types of side effects but none the less, that could be going on for you. Before discontinuing the med though, talk to your doctor.
