I got Botox for my 11 lines and as soon as it was injected I had a sharp pain run down my nose that disappeared after a few minutes. I had a severe headache for over a week after. My left eye was heavier than my right after and I didn't feel good. It wasn't majorly noticeable so I left it because I wasn't feeling good. Recently I've had numbness/in my swelling feeling in the back of my tongue and throat. Is it possible that the Botox travelled and I have nerve damage?
