Hello and Welcome to ‘Ask A Doctor’ service.
I have reviewed your query and here is my advice.
It seems that the symptoms of swelling of toenail along with pus accumulation and dying of the toe nail occurs commonly due to causes like bacterial or
fungal infection. This condition is known as
Paronychia.
It can occur due to conditions like traumatic injury to the side of the nail like while washing clothes or dishwashing, injury while cutting nail, nail biting habits, overzealous manicure, etcetera.
I would therefore suggest you to
consult a General Surgeon and get evaluated and a thorough clinical evaluation is generally sufficient for diagnosis.
You can be advised to apply a combination of steroid, antibiotic and antifungal ointment over it. If it is painful topical application of numbing ointment and taking anti-inflammatory painkiller like
Ibuprofen can help. Do cool compresses over it.
If the lump is large and painful then
incision and drainage followed by a course of antibiotics and painkillers will help get relief.
Hope I have answered your query. Let me know if I can assist you further.
Regards,
Dr. Honey Arora
