Is it ever unsafe to immerse in a mikvah?
Immersion should not take place if one has any open cuts, sores or communicable diseases (e.g. bronchitis, fever, etc.). It is customary not to enter the mikvah while menstruating or spotting. Self-dissolving stitches are permitted, but if stitches need to be removed, one should postpone immersion until the stitches are removed and the wound is healed. Other questions can be answered by CGCM attendants.
