It's been 4 days since my tooth extraction, and I have an unbearable headache, and bad taste in my mouth.  When I called the doctor two days ago, (the doctor was out, but talked with his assistant), she said that there is no way I could have a dry socket because the bone graft is packed, and there are stiches covering it.  She said my headache was probably due to allergies.  I was relieved, but I am still suffering two days later.  Has anyone had a similar experience?  Any advice?
