Question : About a week ago, I had a tetnus vaccine administered to my left upper arm. My arm was sore for a few days, but now there is a hard bump where the injection was administered and it itches and is sore. Is this a normal reaction almost one week later?

Brief Answer: Due to increased immune reaction Detailed Answer: Greetings of the day Increased immunogenic reaction to vaccination may lead to sore and indurated swelling. left unattended it may go for abscess formation. There is no cause of concern. I would suggest you the following 1. Hot water fomentation- Soak a cloth in hot water and apply over the affected area within the tolerable level, every session lasting 15 minutes. 3 to 4 session per day. It will increase the vascularity in affected area, will lead to localization of swelling and fast resolution 2. Anti-inflammatory like Ibuprofen will be very helpful Follow this and the swelling will start decreasing in couple of days Wishing you happy and healthy life In case you require any further assistance will be glad to assist you Take care Best Regards Dr T Shobha Deepak MBBS,MD
