<s>[INST] Hello, I am an 18 year old male and for the last day or so, I have felt discomfort/ache in my left testicle. I also tend to feel pain in my lower back, and when I touch a special place in my left abdomen it hurts a little. I also have started to get pains in my left leg. I have inspected my testicles continously and there is no lump or swelling, neither does it hurt when I touch them. Lower back pain has always been common for me, but not this feeling of discomfort in the testicle. What can this be? [/INST] Hello, It may be due to testicular torsion. For further assessment, you may require ultrasound scrotum after physician consultation. For pain, you can take tablet acetaminophen. Do regular physical therapy. Avoid strenuous activity. Use scrotum support. Hope I have answered your query. Let me know if I can assist you further. Regards, Dr Shyam Kale, Family and general physician </s>
