Hi,
Thanks for writing to us.
Please do not squeeze your boil as it can lead to further infection and the area later on may heal with pigmentation. Instead of using icthamol,I would suggest that you do warm water compresses over affected area and apply an antibiotic cream like
mupirocin. If its a small boil it would resolve with
topical medication only but if its a deep one then, please consult your doctor so that an antibiotic like
amoxycillin which is considered to be safe in
pregnancy can be started.
Hope that helped.
Take care
