Please don't take what I am about to say the wrong way, I am very sincere in my desire to help. You said you pray and turn your life over to God on a daily basis. If you TRULY turn your life over to God you should not have to repeat it every day. Now, having said that, the next time, try letting go and letting God handle it 100%. My granddaughter suffers from headaches, hers is caused by having a sumo tumor. Nothing works for her either except having a spinal tap to relieve the pressure. Have you been checked for this disorder? Also, have you considered your medication? It could be one or more of the medications you are taking could use a change in the dose or you could be having a reaction to one or more of your meds. Have you been tested for allergies? if not, please consider doing that. Something is obviously causing your pain, medicine is a practice of the process of elimination, it sounds like you have done a lot to find something to ease your pain but leave no stone unturned in finding the cause. It could be such a small thing that is at the root of your problem, something as small as a single food allergy can reek havoc in one's life, Or, an allergy to the dye used in foods and materials can be the culprit. And like it or not it could all boil down to being psychosomatic. Stress, depression, and anxiety are no stranger to chronic pain, making the situation worse. I see where you have tried a multitude of self-help techniques and none were successful. I personally, use help healing, prayer, and mind over matter which has helped me with my pain. Self-help is not for everyone, you need to be very dedicated and you need to be totally open about it. Believe strongly in what you are doing, pick one technique and stick with it. One that you can be completely dedicated to. Keep the faith, work your self-help program, and get tested for allergies and have your Dr. evaluate your medication. I wish you all the blessings that God brings you, and know I will remember you in my prayers.
God never promised to heal anyone. All he, (she), promised was to be with you in your time of need. Try asking for Jesus to send you his love to help you heal yourself. Just sayin', that's what worked for me. Love and Blessings
