thank you for choosing HCM,
may lead to thrombus
formation in leg arteries which will cause claudication pain in legs on walking, relieved by rest initially but continues even after rest if worsened.It may also lead to leg ulcers
.Its called Buerger's disease or thromboangitis obliterans.
Strict absolute ceasation of smoking halts the disease process
Applying warmth and exercise like air-cycling will increase local blood supply
medications like aspirin
But since there is complete obstruction surgical care is a must.
It may worsen if you neglect.
Kindly visit a vascular surgeon immediately.
Feel free to ask if you have any doubt.
