How to manage pus-filled infected bumps after an insect bite?

This Premium Q&A, reviewed and published, features a real conversation between an iCliniq user and a physician.

Patient's Query

Hello doctor,

Some insects bit me and I have got an infection because of scratching it and now my lower leg is completely filled with these bumps with pus in some of them. I have been prescribed antibiotics and allergy medication as well as an ointment. Is there anything else that could be done? It is most likely an ant bite which got worse after I scratched it.

Hello,

Welcome to icliniq.com.

IgE (Immunoglobulin E) is elevated, indicating an allergic reaction or parasitic infection. ESR (Erythrocyte Sedimentation Rate) is also elevated, suggesting a chronic infection.

Are there symptoms of fever, stomachache, a history of hives, allergic dermatitis, or atopy? Are there any aggravating factors, insect bite reactions, or signs of oozing, burning, or pain?

Use Fucibet cream (Fusidic acid and Betamethasone) twice daily for seven days, along with the prescribed treatment: Augmentin (Amoxicillin and Clavulanic acid) and T-Bact (Mupirocin). Clean the affected area with Povidone-iodine and normal saline using a gauze piece. Consult your specialist doctor, discuss with him or her, and take the medicines with their consent.

I hope this helps you.

Thank you.

Patient's Query

Hello doctor,

Thank you for the reply.

Nothing except there was burning on the first day then after using the ointment that went away. My foot is swollen and walking is slightly painful but this has never happened before. I am someone who has an allergy to dust but other than that everything is normal. My prescribed antibiotics are about to get over (tomorrow is the last day) so after that is over anything else to be done or to only continue the ointments? And should the area be left open or always covered? I have attached a photo of what it looks like since I started medication.

Hello,

Welcome back to icliniq.com.

Do not cover the lesions. Continue Allegra (Fexofenadine Hydrochloride) tablet, T-bact, and Fucibet cream. Add tablet Zifi (Cefixime) 200 mg twice daily for five days. Or instead of Allegra, you can take Atarax (Hydroxyzine dihydrochloride) 10 mg thrice daily for seven days. Rest continue the topical creams. Do you have a stomach ache? History of parasitic infection? Fever?

Patient's Query

Hello doctor,

Thank you for the reply.

No stomach ache, or fever. No parasitic infection history either. No other symptoms other than the lesions on skin and swelling and discomfort when walking. Are the lesions showing signs of improvement? How do I exactly know that it is healing? Would there be a change in color or something like that? Because it is not increasing it is just flattening now and turning this color. It is on both legs right and left in a similar pattern. I have uploaded more pictures to show it.

Hello,

Welcome back to icliniq.com.

I have reviewed the pictures (attachment removed to protect patient identity). The lesions have improved with the previous treatment (antibiotic course and topical application). However, it may take a few weeks for complete resolution. If there is pain, take Tablet Emanzen D (Serratiopeptidase with Diclofenac sodium) twice daily for three days. If there is a burning sensation, apply a soothing lotion after bathing for 10 days.

Continue the prescribed treatment, and the lesions should heal within one to two weeks. Maintain antiseptic precautions. Avoid scratching, rubbing, popping, or pricking the lesions, as this can lead to secondary bacterial infection.

I hope this helps you.

Thank you.
