Hi, I am suffering from a severe headache for the past few weeks. It becomes worse in the morning. When I wake up in the morning, I sweat a lot which is often accompanied by dizziness. Then I will have severe headache which reduces on the application of balms. I have read a blog which states that botox is effective in treating headaches and excessive sweating. Is there anybody over here who has done this treatment before? Please give some genuine responses. Thanks in advance.
