I'm a 58-year-old diabetic. Is it safe for me to remove it at home myself?

It might be perfectly ok to use the above recommendations as first aid if your injury is minor and you have good blood sugar control. A few important things for you to remember: 1) clean your hands and the area really well before attempting the glass removal, 2) remove the glass completely, 3) clean off and dry the area of the cut after glass removal, 4) apply an antibiotic ointment over the area, 5) apply a bandage or a band-aid, 6) and watch the area for healing or signs of infection in the next 1-2 days. If you notice worsening of pain, swelling, pus, or redness in the area, you will need to go for a follow up with your healthcare provider. To improve chances of a quick recovery, stick to a high quality diet of lean protein and low-glycemic foods, as elevated blood sugar impairs wound healing.
