The dog scratched my leg, and the doctor asked me to take three doses of the injection (on days 0, 7, and 21). I took the first dose last Monday (18th September). The next dose will be on the 7th day, and the third dose will be on the 21st day. During the consultation, the doctor asked if there was any pain or irritation at the scratch area. I said no, so the doctor suggested only three doses. However, today I feel some pain at the scratch area (which may or may not be significant). Due to panic, I wonder if there is any issue with taking four doses of the injection, even if there are no visible issues. Please advise.
