Why might my inner thigh be hurting without any apparent injury?

Reviewed by Yoshinori Abe, MD

Internal Medicine

Inner thigh pain without a clear injury is often caused by three main issues: a hernia, sacroiliac joint dysfunction, or irritation of the saphenous nerve. A hernia occurs when tissue pushes through a weak spot in the groin, creating a dull ache in the inner thigh. Sacroiliac joint problems radiate pain from the lower back into the thigh, while saphenous nerve irritation produces burning or tingling along the inner leg.

Because these causes require different treatments, identifying the source of your pain is the critical first step. A free, instant, online symptom check can help you narrow down possible conditions in minutes and guide you on whether to see a doctor, what type of specialist to consider, and which questions to ask—saving you time, worry, and unnecessary appointments.

Explanation

Inner thigh pain can be confusing, especially when there is no clear injury. Here are some possible reasons:

Hernias can occur in the femoral or groin region and may cause pain and swelling to the hip, thigh and groin region.

Intramuscular Lipoma: This is a lump made of fat inside the muscle that can cause pain. However intramuscular lipomas are very rare. Sometimes, these lumps can be painful even if they are not very big.
Sacroiliac Joint Disorder: This joint is in the lower back, near the pelvis. Issues with the SI joint can cause pain in the leg, including the thigh.
Saphenous Neuritis: This is when a nerve called the saphenous nerve gets irritated. This nerve runs down the leg, and when it is inflamed, it can make the inner thigh hurt.
