Patient have multiple health issues.

Dear Doctors, I am writing to seek medical assistance for my uncle, who had a kidney transplant in January 2024. He developed gangrene in the big toe of his left foot, and despite undergoing angioplasty for artery blockage, the toe did not improve and had to be amputated. Unfortunately, the area continued to appear black, which led to a second and then a third amputation that removed 40% of his foot.Now again doctor suggesting for another amputation . The doctors have assured us that blood flow is present, but the tissue remains black, which they attribute to the steroid medications he is taking following his kidney transplant. We are very concerned about his condition and would appreciate any guidance or further recommendations for treatment. For additional context, my uncle had a heart stent procedure in March 2023 and had his gallbladder removed in November 2020. Thank you for your attention to this matter. Sincerely, RAMKRUSHNA 63xxxxxx77
