[|Human|] A 29 year old male presents with extreme burning and cramping pain upon exertion in the lower limbs. The patient is a competitive marathon runnerand recently ran the New York marathon despite the pain. The patient reports that the pain coincides with the start of physical activity. When the pain was first noticed, it subsided almsot immediately after the completion of physical activity. Over time, the pain has become more acute annd now it takes some time after the cessation of activity for the pain to subside. The patient also reports that recently numbness and and extreme weakness of the calf will result after sustained physical activity.
[|AI|]  Hello, His symptoms could be related to a pinched nerve. Another possible cause to consider would be a muscle disorder or chronic venous insufficiency in the lower limbs, or a connective tissue disorder.  For this reason, I would recommend consulting with a neurologist for a physical exam and some tests: - nerve conduction studies- a Doppler ultrasound of the leg vessels- CPK plasma levels-complete blood count, PCR, ESR for inflammation-A SOT tier.  You should discuss with your doctor on the above tests.  Hope I have answered your query. Let me know if I can assist you further. Take care Chat Doctor.
