Hi! Good evening. I am Dr Shareef answering your query. From the history of yours, it seems that you have got a sebaceous cyst on your thigh which oozed white liquid. I would advise you to see a general surgeon in your area for a proper clinical diagnosis, and a possible excisional biopsy of the same to confirm the same. Till then, please avoid fiddling with the lump to prevent an infection and abscess formation. I hope this information would help you in discussing with your family physician/treating doctor in further management of your problem. Please do not hesitate to ask in case of any further doubts. Thanks for choosing health care magic to clear doubts on your health problems. Wishing you an early recovery. Dr Shareef.
