[|Human|] Hi I knocked my leg a few weeks ago playing cricket, originally it was very bruised and a sharp pain, now the bruising has gone but a large indentation remains on the shin bone, this still gives a sharp pain when touched, also if I touch above the indent it gives a tingling lower down my leg and a weird feeling that feels like something is moving under the skin, I also feel a slight numbness in my foot and on the affected part of the leg Cheers
[|AI|]  The shin-bone lies directly under the skin. There is no muscle between the shin-bone and the skin. Any injury over the shin causes direct injury to shin-bone. sometimes it causes blood collection under the periosteum (thin covering over bone) of shin-bone. It causes sever pain and indentation for 1-2 weeks. The superficial perineal nerve lies on lateral part of leg near the shin-bone and give sensory supplies to some part of leg and upper part of foot. If it gets injured, causes numbness on upper part of foot and some part of leg. Rest, icing, local application of non-irritant analgesic gel and anti-inflammatory analgesics such as ibuprofen will decrease pain and swelling. Nerve enhancer such as pregabalin will be helpful in decreasing numbness. Hope this helps. Hope this answers your question.
