Suggest remedy for swelling,pain and redness in right leg and ankle?
Patient: my right leg and ankle (fused from an old accident) has been red, hot, very swollen and painful. one doctor did an MrI said it was vascular no infection. another treated me with antibiotics for 10 days. No improvement.I am seeing a vascular surgeon this Wed. I feel sick, weak, tired. Who is best suited to diagnose and treat me.I have had 5 surgeries on the ankle to help the pain over 20 yrs. I am 80 and just had colon cancer surgery. Doctor: It needs to be investigated. With a history of  surgery for colon cancer,possibility of secondary deposit should be ruled out. A biopsy from the hot spot may have to be done. PET examination  should be helpful.
