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.
If a person has received stitches, they should be given instructions for taking care of the stitches and wound, and be given an approximate date to have the stitches removed. A sample of such instructions is as follows: Keep wound clean and dry for the first 24 hours.
