Hello! Related to your symptoms I think this is cat scratch disease. You should know that cat-scratch disease (CSD) is a common and usually benign infectious disease caused by the bacterium Bartonella henselae. Anyone who owns a cat or interacts with a cat is at risk for contracting cat scratch fever. You have an increased risk of becoming seriously ill from cat scratch fever if you have a weakened immune system. I think you should be aware of common symptoms of cat scratch fever like a bump or blister at scratch site, swollen lymph nodes near the scratch site,fatigue, headaches,a low-grade fever. If you have these symptoms you need to do a physical examination by a doctor and PCR test for bartonela henselae and to take antibiotics (azitromicin,or bactrime) if need it . During this time,you can wash with soap and water (as you have done) and apply local antiseptic (betadine solution)and local antibiotic crem (eritromicini if you aren t allergic) in the scratch skin because there exist inflamation signs. I hope my answer help you. I wish a quick recovery.
