<s>[INST] On Wednesday I had a routine physical and was given the Tetanus Shot on my left arm... today (Friday) I noticed that I have two small red bumps on my arm about a fingertip apart (one of the red bumps is from the injection of the needle). I also have faint bruise under the bumps (bruise is shaped like a line that extends to almost my armpit). In addition, my arm is sore, at times the bumps sting, and shoulder/clavicle is sore). Are these normal side effects after having a tetanus shot?Background: Gender - FemaleAge - 25 years oldHeight - 54Weight - 115 [/INST] HiT hanks for posting your query on ChatDoctorI appreciate your concern towards the painful bumps following the injection of tetanus toxic. These are not the normal side effects after having In T.T. Apparently the features described are suggestive of inflammation of the soft tissue cause by infection resulting in abscess formation. Take some NSAID painkiller like Ibuprofen for the pain and swelling, get examined by a doctor for proper assessment and possible incision and Chat Doctor. Hope this answers your query. Regards. </s>
