Hi all. I am nervous to ask this question incase the answers are bad. Kitten turned insulin diabetic last December. I injected her just under shoulderblades. She is now swollen in this area esp on one side. Her IM examined her last month ,and told me to monitor the swelling. So, I am now rotating injection sites and avoiding the swollen area. I now notice red marks in the areasI inject her. I happened to show the vet tech at an injection demo appt. last month and she said she had no idea but to monitor. The marks went away because I avoided this area. But now I see more red marks in my new injection sites.The red marks look like little red bruises. I use a blotted alcohol pad to part the fur so I can see the skin. This is a tip suggested by the hospital tech. The alcohol dries quickly after and moves the fur. I can actually see what I am doing now. So, I am not sure if there have always been red spots or just that I can see the skin now. Is this an allergic reaction to insulin or silicone in the BD syringe? Am I hitting blood vessels? Am I bruising her when pulling fur up to tent? Am I shooting in wrong spot? Is the swelling scar tissue? It feels like thickened skin. I will be bringing her in for an exam and some testing soon, but I am looking for some help. These red marks have me very worried. Any input would be appreciated.
