I also received an injection over a year ago, for a respiratory infection. The site in which it was given, (hip area), has quite a large indentation from it. My question to anyone who can answer is, has anyone noticed an indentation anywhere else on thier body. (Not counting where the injection was given)???? I have noticed an area on the opposite side of my body(leg area) an indentation. Getting quite nervous about all of this. I also am noticing shortness of breath. Thank you.
