Wishing you good luck on the biopsy and hope things get much more better for you! The sleep study test! Just had that done! You may get a laugh at yourself the next morning when they take out the wires. I looked like Frankensteins Bride when I went into the bathroom and saw myself in the mirror. All that paste they use in your hair make it stick up everywhere! Not a painful test though. Very easy!
Hope your biopsy turns out okay and I wish you good luck! Cyber hugs heading your way!
