Injury or trauma: causing muscle strain/injury is the most common cause. You should be aware if this has happened. More worrisome causes in a young man your age might be a blood clot in a vein or even obstruction of lymph flow higher up...perhaps in your pelvis. Cellulitis would show skin infection signs. There are numerous rarer causes. Ice it; watch it a day or two. If it doesn't improve, see your doctor.
