Treating a toe infection

As a result, I got an infection in the nail and had to take a course of antibiotics. But the nail died and I had to have it surgically removed. My cut was slow to heal until I took my pharmacist’s advice and covered it when showering. However, while the nail has started growing again, the wound is not fully cured.
I am taking Eltroxin on a daily basis as I have had my thyroid removed. I would like to know about alternatives to this drug. I am 60 years of age.
