Hi! Good evening. I am Dr Shareef answering your query. Although it needs a clinical assessment with related investigations to diagnose the condition, possibly it might be some kind of vascular malformation (hemangioma), which got compressed on pressure, and took time to come back to its formal position. If I were your doctor, i would observe these for a few more days, and then decide on further course of action if it persisted. 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. I wish you an early recovery. Dr Shareef.
