Doctors my father is facing issues in his leg. His leg below the knees turns a little bit blue and swells alot. He consulted one private dctr and he said he needs to have a operation as there is 2-3 gaath in the veins/leg. My father is done with the operation in safdurjung hospital, delhi. 2 months are completed but the leg is swelling more than before. My father is now scared of going to govt hospital again for any treatment. Please help me what should we do please.
