How to treat a toe nail injury ?
Thanks for your query.
I don't consider there is a need to worry here. Both the probable diagnosis your Podiatrist mentioned are known to spread but not to the extent where waiting for 3 to 4 weeks would be a serious risk.
I would ask you to take a good care of the lesion meanwhile, by cleaning it with a antiseptic solution like Cetrimide twice daily.
If there is pus collection again do consult the doctor for the drainage of the same.
Hope I have answered your query. If you have any follow up queries I will be available to answer them.
