Yesterday i injected 2cc's of deca into my shoulder and did not aspirate before injection. When i was injecting my shoulder i could feel the deca spreading thoughout my shoulder it felt like, there was some blood that came out of my shoulder but nothing to big. When i looked at the syringe it had a little drop of blood inside and the needle had blood on it to. Today my shoulder seems tighter than normal after injection but it also has a bruise and is swelled up. what can i expect from this now? what happened did i hit a vessel? How long should the swelling to before it goes down?

thanks for reading and responding
