Hello dear, Thank you for your contact to health care magic. I read and understand your concern. I am Dr Arun Tank answering your concern. Small blood clot on the skin never requires any treatment. It will go away with its own. This fact was known to your doctor so they given you fusidin H cream. It is a antibiotic cream used to treat bacterial infection. Sinus medication never causes such blood clot. It has probably some different origin of infection. I advice you should examine yourself by nearby doctor to know the cause. Small blood clot requires no treatment it will go away with its own. You only have to make good hygiene to prevent infection. Avoid sexual intercourse until you are clear with all this things. I will be happy to answer your further concern on bit.ly/DrArun. Thank you, Dr Arun Tank Infectious diseases specialist, HCM.
