Hello,
Thanks for Writing to Health Care Magic and putting trust in us regarding your Health related query.
I am Dr. Saleha and I have read your message in detail, I understand your concern and will try to help you in this.
I am sorry to know about your problem.
I suppose you didn't seek medical attention after this happened, now it seems that you got germs when thumb got a wound and this wound has got infected now, that's why it's draining puss and smelling bad.
I will suggest you to immediately seek medical attention and get your wound checked up by a doctor. Washing it or applying antiseptic will not help you much in my opinion. You will have to get a complete check up , at this stage you might need antibiotic course and cleaning or the wound off debris and pus.
This might lead to extension of puss to neighbouring parts of the limb and even
gangrene may occur, I suppose it's already necrotising the tissue which is the cause of bad smell.
This can well lead to gangrene
sepsis and
amputation or life threatening issues so it is suggest to immediately seek medical advise and get the treatment started.
I hope this answers your question.If you have more questions, I am happy to answer.
Wish you lasting health.
Regards.
Dr.Saleha Saeed.
