Dear Chuzzle, I am so sorry to hear you're having this on top of all you are going thru. Yes, I get that same 'flu-like' feeling, also burning and numbness. It is so horrible. I do hope you are feeling better this morning. I would suggest the same things mentioned, cuddle up in a warm blanket - put in the dryer to make it extra warm. Use a Bed Buddy and a heating pad. Maybe a call to the dr for something to help w/ the pain right now.
I will continue to keep you and your DH in my prayers. And yes I am praying for a miracle.
God bless. Alice.
