A warm welcome to HCM
Understood your concern.
is a natural process of the body. it occurs either by primary intention or by secondary intention. In practice, wound healing by primary intention takes the usual 7 to 8 days for completion. Hardly any benefit is expected in case of stitch removal after a prolonged period, what ever may be the depth of the wound. But that does not mean the wound will remain opened. it heals naturally, if proper apposition of wound margin is maintained; there comes the role of strip plasters.
This type of problem is seen, particularly if the stitch is on a fatty area like buttock or a fatty abdomen etc.
The earlier one start becoming ambulatory, the more rapid is the recovery of general well being.
If the white blister
contains pus, it requires a culture identification of the organism, if present.
The best advice at this point is to stay adhered to your treating doctor, and she will be recovered. it may take another 1 week or so after stitch removal.
Wishing her a speedy recovery.
