Hi My father is 67 yrs old , underwent achilles tendon repair last Oct 2016. Open surgery was performed with 8 weeks of cast. He is diabetic ( fasting range 110 to 125 , post range 150-170) since 2-3 years now. His surgery incision by Feb was 98% healed. There is this small hole still open and every day oozes clear fluid ( only 2-4 drops) after 10-15 mins of daily walk routine. Culture test of fluid was done, and is put on antibiotics (ceomox 625) since last 2 months. The small hole still oozes fluid . Can you suggest if this could be something else other than infection or related to inner area of tendon?
