Suggest Treatment For Asthma And Hives On Spine

Hello,I've recently had my wisdom teeth removed as of friday morning. I have since stopped taking medication. My disolvable stitches have disolved on one side a little early and I think this is due to me using scope mouthwash. I am not bleeding, but am curious about possible complications I should look out for. Additionally I have a history of allergies to pollen and many mamals such as dogs, cats, and horses. I also have asthma. As of tonight I have developed a hive on my spine. I am worried about what this could mean.
