My sister is getting swelling on her face in the following manner:- On first day face is feeling burning sensation. Second day its getting swollen up. On the third day skin is getting somewhat died and blacky and then it starts coming out and then new skin is coming. This cycle is getting repeated over and over again for last one month and her White Blood Cell count has also become 19000. What problem she is having ?? Is it Agioedema or something else ??
