Coughing right after test-e injection

[Mrgilmore]

Hi guys,
yesterday I took a shot of 1cc of test enanthate in my left quad. It's not my first cycle, I injected several times before in both quads and glutes and never had this problem. I did aspirate and there was no blood before pushing the oil.
Right after the injection, I mean about 30sec after, I had a coughing for about 2-3 minutes. We're 12 hours after the shot and I can still feel a weird feeling, not painful, when I take a deep breath.
What du you guys think ?
First I thought I passed trough a vein, but there were practically no blood after removing the needle.
