Hi- I received botox to my forehead one week ago. About 5 days after, I experienced runny nose and cough. Today- 1 week later- the cold symptoms continue and I have a heavy and tingling feeling in my forehead (not painful but strange and a bit annoying). Are the cold symptoms a side effect of botox- if so when will this end? When will the heavy/tingling stop? Thanks. Hoping to feel like myself again with the added bonus of a smooth forehead
