Hi, Cannot say in your particular case. AND there is not a direct connection from the back to the face. Or to the shoulder and arm. Elevated BP  needs treatment. the pattern of the pain would require a bit more information and it generally shows where the problem is. Hope I have answered your question. Let me know if I can assist you further. Regards, Dr. Matt Wachsman, Addiction Medicine Specialist
