another possibility of poor healing is due to poor circulation.
in some patients who have diabetes or poor blood vessels or arterial stenosis, not enough blood can get to the wound to help with healing.
an angiogram or ultrasound of your arm can check for proper blood flow and circulation to the hand
if there is a blockage, some patients need angioplasty to help reduce blockage and improve blood flow.
many hospitals have wound care clinics to help with wound healing and wound healing doctors and nurses
manuka honey or Medihoney can help a wound heal
Silavdine ointment 1% can help the area
there are other creams like Santyl which can help with debridment
on your finger, it is important to protect the hand and not use the hand and finger which can disrupt healing if you use the finger.
increasing your diet's protein intake and vitamin C in take can help your body make more scar tissue in the area and help with healing as well
