What could be causing pain in my left testicle and when should I be concerned?

Pain in the left testicle can have various causes. One common cause is a varicocele, which is a collection of veins in the testicle. This can cause discomfort or pain. Another possible cause is the position of the testicle; if it lies in a certain way, it can lead to pain. Other causes include testicular torsion or epididymitits and should immediately be evaluated by a healthcare provider.

When to be concerned:

• Severe pain: If the pain is very strong, you should see a doctor right away.
• Persistent pain: If the pain does not go away after a few days, it's a good idea to get it checked out.
• Other symptoms: If you notice swelling, redness, or changes in the shape of the testicle, see a doctor immediately

It's important to pay attention to these signs and seek medical advice to ensure proper care and treatment.
