What Are The Side Effects Of Botulinum Toxin -A?

i was injected with Boulinium toxin -A, for urinary incontinience, a few weeks later i started having these strange symptoms: foul odor of rotten suasage coming thru my skin in the stommache ares and from my legs. i've done research and found out that tihs injection could spread to other organs of the body. i have painful and uncomfortable things going on in my colon area along with this foul putrid smell, i also feel that when i eat or drink i can feel something busting forth underneath my skin then comes the foul odor. i never had this problem until i was injected with Botox -A.
