Brief Answer:
Oral antibiotics and some local steroid might be needed to be used

Detailed Answer:
Hello and welcome at "Ask a Doctor" service,

It seems that the skin around the possible bitten area is getting infected. You are having redness spreading on the upper part of the foot. In this case it would be best to use oral antibiotics like augmentin 2-3 times a day and also you can apply local steroid cream to reduce the inflammation (you should not use the steroid unless you start the oral antibiotic because it may make infection worse).

To conclude I would say:
- very likely the bite is getting infected and oral antibiotics would be safer and better option with augmentin the most used one and if you are allergic to penicillins you can take clindamycine.
- local steroids like beclomethasone thin layer twice a day can be applied on the area after the antibiotics are started
- keep the area clean to avoid further infection
- your doctor might also consider your tetanus status and if needed might recommend you tetanus prophylaxis.
- keeping your leg raised as much as you can might help with the swelling and possible pain in the area

I hope this answers to your query.
Let me know if I can assist you further.

Kind regards,

Dr. Antoneta Zotaj,
