My mother who is 84 year old went through toe 4&5 amputation for diabetic foot with gangrenous ulcer. After surgery infection again surfaced for big toe. Last few weeks we started Ayurvedic process with excellent results in wound healing and controlling infection. However process requires cleaning wound on day to day basis which is very painful. Can we administer local anesthesia before debridement and wound dressing. If yes can it be administered at home?
