<s>[INST] I fell about 3 weeks ago... I am 35 year old woman. After the fall I had an immediate bruise about the size of a dollar...It was more linear than round. It was sore to walk on for a few days but hey I am 35 and fell on concrete bashing my shin on a concrete step. I have not gone to the doctor just rest, ice, elevate and Motrin. Last night I noticed a hard dime sized lump. It is not able to be moved and is solid not fluid filled. Should I have it looked at or just wait. It is tender to touch and I am not able to kneel on it at all! It is raised more than my knee so when I kneel my weight is on this lump and hurts. Thank you in advance for your time. [/INST] HI,Welcome  to HCM.Based on the facts of your query,you  seems to suffer from-Leg Shin Cellulitis with  Resolving Hematoma.Seems you started your activity early as compared to the trauma/hit you had from the Concrete Step.Tenderness indicates Cellulitis there still.As its 3 weeks now,You should take your doctor's opinion to assess the cause of the delayed regression of the tender bruised lump on the shin,ONLY if you find after 1 week that it has not regressed or it is increasing.Possibility of the bony injury needs to be ruled out by Xray and Usg of the lump and by Surgeon's Second Opinion.Hope this reply would help youWelcome for any further query in this regardWill appreciate writing your feedback review comments,to help the needy patients like you at HCM.Good Day!!     Dr.Savaskar,Senior Surgical SpecialistM.S.Genl-CVTS </s>
