I have been diagnosed with a small hydrocele in my left testicle and a Reticulonodular density in the lower left lobe of my lung. My groin and left tesricle hurt when i either move too fast or any activities such as running or longboarding. also My chest has crushing pains all day , my abdomen , into my sides and back as well. I've lost about 12 pounds . And I lost my appetite for the most part. I feel like there could be something more seriously wrong than just their diagnosis.
