Welcome to Healthcare Magic.
Its 15 days since you were operated. So what are waiting for ?? Go and take bath immediately my dear. We recommend washing and taking bath the very next day after these kind of minor surgeries. Actually it is always better to maintain proper hygiene by cleaning and washing as it prevents the secondary infection of the wound. The important thing to remember is that the wound area should not be wet for long time.
You should also resume your daily one hour walk by today itself. By walking also you get good wound healing
For sweating you should not take any medication, rather can change the gauze pad frequently to preventing the same.
Hope this information will help you.
With Best health wishes,
Dr Sanjay K Kanodia
