Brief Answer:
Nerve injury.

Detailed Answer:
Hi,
Thanks for asking your query.

Many times when a person has pain in right leg after cariac XXXXXXX it is due to irritation of a nerve in that area called the saphenous nerve. This condition, called “saphenous neuralgia”, is sometime seen after incisions in the groin for surgery on the femoral artery and it can also be seen after XXXXXXX procedures, during which a needle and catheter are placed into the femoral artery. Inflammation in the area is thought to irritate the nerve and cause the symptoms of pain shooting down the thigh. Patients can experience pain along the inner aspect of the thigh and it can also extend down to the inner aspect of the knee. The pain is often described as a “shooting pain” or an “electrical shock kind of pain.” It can also be associated with numbness in the same area. Some patients have both numbness to the touch and shooting pains down the inner thigh. The diagnosis is usually a “clinical diagnosis.” That is to say, CT scan or an ultrasound test (for example) will not show irritation of the nerve. It is important to first rule out a problem with the artery (such as a pseudoaneurysm or an infection, for example) and vein (such as a blood clot for example). You mentioned in your question that color doppler was normal so most likely its neuralgia. The diagnosis of “saphenous neuralgia” is usually made by a vascular specialist after ruling out any other abnormalities of the artery and vein.If you have not been seen by a vascular surgeon, I recommend that you do so. In my experience, the discomfort associated with “saphenous neuralgia” usually improves or resolves completely. Frankly it mat it take many months, however. Sometimes consultation with a neurologist is appropriate.

Suggestions=
Ask your cardioogist to add pregabalin 75mg once daily along with anti inflammatory. Pregabalin is good in neuropathic pain.
MRI should be done to see functioning of nerve.

Thanks.
