<human>: 2 days ago I noticed pain on my lower shin, I thought I bumped it because it felt like a bruise.Today it has turned into a red,swollen area about 3 inches long and 1 1/2 wide.Feels like a bruise still with tingling in my foot below it.What could this be?
<bot>: Hi, It occurs commonly due to medial tibial stress, or can also occur due to excessive physical exercise or increased activity that overworks the tendons, muscles & bone tissues. Do not get overweight, avoid overdoing your exercises, wear proper shoes which have soles that can absorb friction & shock. Take calcium tablets as a supplement. For relieve you can apply pain relieving ointments, balms & sprays. Medications like NSAIDs, Naproxen are effective. Visit ER, get X-Ray done to rule out any hair crack or fracture that may require medical attention.  Hope I have answered your query. Let me know if I can assist you further.
