My mother was operated for perianal fistula in july last year. Since then she gets on-off swelling in her ankles and feet (sometimes low sometimes high), which gets worse on walking. Her urine test, KFT,
LFT, ultrasound all are normal. Has it got anything to do with the operation?
She's on the following medicines- NSAIDS for joint pain, Pregabalin for nerve pain, Multivitamins, Antacids and proton pump inhibitors. Was on antibiotics earlier but not now.
