When the Dr injected the Botox it hurt so freakin bad. When I got the injection on the other side it didn't hurt. I hope I did the right thing by doing this. The Dr said it will take 3 to 5 days to work. Right now my left side were my pain is feels aggravated. I pray this works. I spent a lot of money. Fingers crossed. I am also still on clindamycin antibiotic for this pain in my face. Thank you for listening. smoovechic
