Is clear liquid leakage and dried yellow crust at a toe wound site a sign of infection?
you should visit your doctor as soon as possible
Even minor foot injuries may evolve into serious trouble in patients with diabetes, particularly if neuropathy has already been established. I can't be sure just by looking at the picture but it doesn't look that bad. What worries me the most is the fluid that comes out of the injured area. Fluid production usually means infection or inflammation.
That's why a close look by your doctor is recommended. Until then you can try an antibiotic cream. Be sure to keep it clean and dry.
Hope I have answered your query.
Let me know if I can assist you further.
If it's getting better then you probably can continue the same treatment. If it's not getting better and particularly if you've got diabetes for more than 5-10 years then you'd better let a doctor have a close look.
