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.
Simply sit with your bottom in the warm water until it no longer feels warm. Pat yourself dry gently. Dump the water into the toilet. Use the sitz bath for 10 to 15 minutes at a time, 3 times a day, for the first week after delivery. Your stitches will dissolve in 10 days to 2 weeks. They do not need to be removed. You may feel a sticking or pulling sensation as your stitches heal.
