He had his 13m injections, one is each leg. The (his) right leg is OK but the left has a big red mark around it, and is swollen and tender (he flinches) and the swelling is pretty hard and quite a big area, the whole of the side of his thigh rather than a pea size little bit. Is this normal? Do I need to see/ring anyone? Injections were yesterday, I only noticed this this evening. Thanks
