### output:

Hello. Thanks for writing to Chat Doctor. It is unlikely that the current swelling and pain is due to the cat scratch as quite a lot of time has elapsed since then. If it was as a result of the cat scratch, it would have appeared within 1-2 weeks. The current medication you are on, Supreme 500g, if the contents of it were available, it would be more helpful. Right now I can think of the following possibilities:1. A sprain in the right leg - either in near the knee or ankle, which was caused by an injury subtle enough for you to have not noticed it.2. An abnormality of the bone - infection or any malignancy (unlikely if you are more than 30yrs of age) 3. An infection of the skin or cellulitis - likely if you have had any injury or even without an injury especially if you have diabetes, with uncontrolled sugars.4. Varicose veins - if your job involves prolonged standing or are very overweight or have any other condition affecting the valves of the veins of the legs. You need thorough examination of the leg and blood tests like a complete blood count, an HbA1c, random blood sugars - mainly in addition to other usual tests that your doctor may ask for. In addition to this, a venous Doppler or ultrasound of the leg and X-ray if necessary may be required. Hope this helps. Wishing you a speedy recovery. Chat Doctor.
