Hi, Welcome to Health care magic forum. It appears that the changes are due to the diabetes, heart failure, or hypertension, or deep vein thrombosis. I advise you to consult a physician for diagnosis and treatment. You may need to have an E.C.G, color Doppler,and other tests for confirmation. Take more of green leafy vegetables, pulses, sprouts, and protein rich foods to have good recovery, and resistance . wishing for a quick and complete recovery. Thank you.
