Hi! Good evening. I am Dr Shareef answering your query. The lump on your elbow could be due to collection of blood caused by the kick by the horse. This would normally get absorbed in a few days if there is no more active oozing. If I were your doctor, I would advise you for an anti inflammatory drug along with a proton pump inhibitor for a week to ten days for a symptomatic relief and control of the inflammation. Also a cold compress and rest to the elbow with a supporting sling would add to hastening of the improvement. If it persists or the pain increases, I would then advise you to consult an orthopedic surgeon in your area for a possible radiological investigation and further management. 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.
