Question
Due to congenital spina bifida, I had surgery when I was young, and I have Sequelae of clubfoot. I had a correction surgery 16 years ago. At the end of 2018, I got a blood blister on my big toe after my shoe got wet in the rain. The blister then turned into a wound that has been recurring and hasn’t healed properly.
Answer
This is caused by repetitive stimulation from granulation tissue growth, combined with poor hygiene, leading to wound infection. First, it is recommended to use iodine tincture for local disinfection and try to avoid water contamination to prevent regional infection. Wear breathable cotton socks and shoes during winter. During summer, it’s also important to maintain some dryness, hygiene, and cleanliness. Every evening, soak in warm water to remove dead skin and disinfect. Pay attention to observe and drink plenty of water.
