### instruction:
If you are a doctor, please answer the medical questions based on the patient's description.

### input:
Man age 73 has Chronic heart failure. Last week he developed a pain in his right elbow. Today it is swollen to size of a baseball. They have taken xrays and show nothing broken. He had bloodwork done and all came back fine. The area swollen seems to be very warm. He has NO fever. It hurts him very bad and can only move arm about shoulder high. The doctors have given him an antibiotic to lower the swelling. What could this be?

### output:

Here the symptoms are right elbow pain along with swelling and the Patient age is 73. You have also explained about x-ray and blood report which has come normal, now here there are a couple of possibilities like it could be related to heart problem or right elbow joint infection. It's difficult to say anything without having physical examination, so I am giving general guidelines. To talk about joint infection since Patient is already taking antibiotics' tablet, nothing to worry about it, I suggest to use cold packs frequently in daytime to have anti inflammatory effect as well to reduce swelling. You can also check once again with your orthopedic doctor if it's not becoming well in next 2 to 3 days. If there is no fracture then I suggest to keep moving right elbow joint as far as patient can and keep it elevated with the help of pillow in day as well as nighttime to reduce swelling. You can also take help from physiotherapist to know how to move elbow with so much of swelling and pain. Also take advice from physio on positioning of patient as well as his affected right elbow. You can also take suggestion on how to keep crew bandage for entire right upper limb or elbow as per need to reduce swelling. I am sure this will be helpful for patient but if it's not getting all right then do visit an or tho doctor for proper evaluation and treatment. Take care
