Hi! Good evening. I am Dr Shareef answering your query. Even though a clinical assessment is required, from your history it seems to be more like a spreading subcutaneous hematoma due to the blood not being able to clot by the action of clexane injection which prevents clotting. If I were your doctor, I would first advise you to discontinue the clexane injection for the time being after consulting the doctor under whose guidance it was started, and then go for all the investigations like a clotting profile, and the scan for which you were waiting. I would also start a prophylactic antiobiotic in case this has to be aspirated out. All the management would depend on the reports of the investigations. 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.
