What Causes Dark Colored Urine And Dull Pain In Testicle?

Dark colored urine, probably blood. Slight to moderate dull pain in one testicle, moderated today. I had a stroke 2 1/2 years ago, recovery about 95%. I feel lightheaded when I wake up. Meds, Aggrenox twice a day, generic Welbutrin 150 mg once a day, atorvastation 40 mg once per day, Vit D 2000 units a day, Multi Vitamin once, B complex once, don t over use any. Recent moderate alcohol use before bedtime, pseudo ephedrine to help sleep. Should I seek medical assistance if dark urine continues for another day?
