This would be maddening! The only thing I can think of is that there was a beginning to the problem (5 months ago). I would think about what happened back then; a new pet, a new medication, a new soap, a new living environment, a stressful situation? Might be you are allergic to something. I'm sure you've prayed to ask God what is causing it; I pray He will answer you ~ or give the answer to your doctor!! I am so sorry you are suffering. I will be praying for you as well. I love you, sis!
