A thigh strain or quadriceps strain is a tear in one of the quadriceps muscles at the front of the thigh. It can range from a mild discomfort to a full blown tear of most of the muscle resulting in severe pain and inability to walk.
The breakage of the stitches starts within 2 weeks of the stitching but if you want the complete stitches to disappear then the process of hydrolysis or the enzymes in our body do that in a period of 60 days and therefore it approximately takes up to 2 months for the stitches to get dissolved.
Nonabsorbable stitches should be removed several days to weeks after their placement, depending on their location. For instance, sutures on the face should be removed in approximately 5 days; sutures on the legs and abdomen, in 7 to 10 days; and sutures on the back, in 10 to 14 days. Strips of adhesive tape may be placed over the wound to help support the tissue while it is healing.
