Welcome, Videolady! I will definitely be praying for a Dx and appropriate treatment, as well. Situations as this one can be scary. But God is interested in your well being.
Remember that our loving heavenly Father watches closely over each of us. It helps me to trust when I remember this: If his eye is on the sparrow, we can trust him to care and supply each one of our needs too.
Blessings to you and yours!
