Transmetetarsal amputation wound sealing problem

Following the amputation of fifth right metatarsal due to a slight injury to underlying tissues and 18 months surface treatment by family MD, two skin grafts applied to the wound initially healed but the common butt joint next to the severed bone remains a slow leaker. Surgeon says it may not close completely, discharging patient.
Being 67 and the only caregiver to a 61 year old spouse, I need to walk for shopping and other errands, living in an isolated rural area. I minimize walking but even a little increases leakage onto sock, this following a nearly 6 month recuperation and curtailed exercise.
Formerally diabetic (type 2) I stopped blood sugar indications following gastric bypass surgery 7 years ago, loosing 80 pounds that remain absent.
Is this leakage damgerous and are there any new developements in ulcer healing available? The leakage site is solid, the skin grafts well fastened but the leakage is worrying me. My (now)former GP failed to realise the developing seriousness of the initial injury and treated the developed ulcer by callous removal but no x-ray. His vacation coincided with a ballooning of the skin over the ulcer location (it was under the sole callous) on the top of the metatarsal. Emergency room examination and e-rays resulted in Osteomelitis diagnosis; reccomendations for amputation followed.

Wound healing has become a dedicated specialty in medicine, and many good hospitals have wound healing centers either within the hospital or self-standing. Instead of seeking advice which cannot possibly in based in sufficient knowledge of a condition which if not treated properly could have dire results, PULEEEZE seek the most sophisticated hands-on medical care available to you. According to what you have said, it appears that you have already suffered the results of less than timely and appropriate care.
