One week post masseter botox and my TMJ has gotten worse?

I had botox in my masseter one week ago for TMJ pain and size reduction. Straight after I noticed a bulge when I clenched, so I went back and had more units injected into the bulges 2 days later. My TMJ is actually a lot worse than it was then, and I am in a lot of discomfort. Should it have taken effect for pain by now? Is it a coincidence or could the botox have made me worse? I lay down and possibly rubbed the areas not long after my first treatment. Could this have effected it?
