I am t6-t7 paraplegic since 2005.I am having a bed sore in my side thigh for over 8 years.. it was healed upto 90% bt the hole was still there.. nw i am dressing my sores once a day with betadine solution and 'drez' an ointment. Now one of my frnd, who is working as a nurse says me to apply the celin 500mg(ascorbic acid) tablet directly to the bed sore by powdering it.Wl it help to heal my bed sore or it wl worsen it?
