I Just Did A Cotton Shot With A Bunch Of

I just did a cotton shot with a bunch of semi old meth cottons of mine (I already know the dangers of cotton shots so no need to give me the whole spill on that) and emediantly after I finished injecting and pulled the needle out I started experiencing sharp/burning kind of intense pain going up and around throughout my arm and injection site. It's been about 5-8 minutes since injection and it still fucking hurts pretty bad. I HAVE used this site and vein very often (about everyday and up to around 1-6 times in a day) for about 3 weeks to a month now without really any kind of break much at all so I'm thinking that that probably has quit a lot to do with what's going on. I'm pretty confident that this wasn't a miss as there is no visible sign of any lump raise and doesn't feel as if there's any fluid trapped inside but does feel very similar to the pain of a missed shot. No real redness so far and the injection site doesn't feel un normally hard or stiff to me either. What could be going on to me right now? ANY/ALL input and ideas will be VERY MUCH appreciated THANK YOU!
