[|AI|]  Hello and welcome to Chat Doctor, A knot like structure between your shin and calf muscles which is painful and sensitive to touch could be due to swelling arising from the nerve. Swellings arising from nerve are usually painful and are characterized by shooting or shocking kind of pain. Imaging has to be done as first investigation. MRI is best suited for soft tissue swellings. This has to be followed by an aspiration cytology wherein cells are aspirated using a needle, spread on a slide and stained with appropriate stains. The stained cells are studied under microscope.These investigation helps to determine the site of origin and nature of the lesion. Thanks and take care Chat Doctor.
