The most common cause of muscle pain the groin is from a strained or pulled muscle. This frequently occurs in the hip adductor muscle group. These muscles include the gracilis, pectineus, adductor brevis, adductor longus, and adductor magnus. The muscles work to bring your leg inward, adducting your hip.
If it is a grade 1 muscle strain, you may feel slight tenderness and soreness. One of these muscles is likely pulled, not torn. In a grade 2 muscle strain, you may feel more severe pain. There may be bruising, tenderness, and weakness. In a grade 3 muscle strain, you will often have bruising and severe pain in the area. In this case, the muscle is likely torn.
When it comes to groin strains, you may have heard a pop at the time of injury and then, noticed swelling immediately after.
However, a muscle strain isn’t the only reason you may feel muscle pain in your groin. The pain may also be attributed to a hernia, prostatitis, epididymitis, orchitis, cancer, hip issues like arthritis, or kidney problems. In most cases, it’s a good idea to get your pain checked out by your healthcare provider. Some causes may be more serious than others, so often, the sooner, the better.
