How To Relieve Pain In The Right Head And Neck After Waking To Puffiness In The Region?

i have pain on the right side of my head near the temple area. I have swelling and puffiness on the right side of my head at the temple region as well. my right eyelid is more puffy than my right. i noticed it one morning some time ago. the right side of my face and head is basically swollen and puffier than my left. i have consistent pain in the swollen temple such that i rub the side of my head all day to relieve the pain. the back of my neck along the right side also has pain. i basically rub and massage the side of my head and right side of neck and traps all day to relieve the pain. i want the pain to go away. my research leads to either tension headache, cluster headache, posture problems, temporal arteritis, kidney problems, diabetes, etc. i have a very stressful professional life as an entrepreneur.
