Hi. Thanks for your query. Noted the history and understood your concerns. History of fall on the side on a hard surface and then limping, hard lump indicate an internal injury due to fall. This should not be taken lightly as impacted fractures do not show more symptoms and signs. Hence the following is needed in your case: Get an opinion of your Doctor and get clinical evaluation, examination preferably by an Orthopedic or General Surgeon. The investigations needed will depend upon the clinical findings which may be X-ray or CT scan of the affected area as this is superior investigations and help to get any internal trauma clearly to plan the further management. Till then continue the anti-inflammatory medications. You may please take Ibuprofen if it suits you. Take full rest ill a proper diagnosis has been made.
