You might have struck a nerve, and possibly caused an infection. You also caused trauma to that area. See a doctor for an exam and treatment. You should also seek treatment and counseling for your drug addiction before you possible kill yourself and hurt your loved ones.

For a start, quit using meth. You probably did not inject it into the vein and may have introduced infection at the injection site. It would be prudent to seek medical and psychiatric help.
