WHY would chewing some ice possibly NOT be good for you? When I was running a rural mail route w/o air conditioning in my car I encountered near heat stroke 3 times. I found carrying a cooler of ice and constantly eating ice prevented my getting overheated like that again. Just be careful. I accidentally swallowed too large a chunk of ice, naturally on a stretch of my route where this is NOTHING for 3 1/2 miles. I just about
passed out, I was seeing "black" when it finally melted enough to slide down my throat and let me breathe.
And, I'm one of these people who is almost always cold. I'm wearing a turtle neck or sweat shirt and blue jeans when others are running around in T's and shorts!!! When I get that chilled to the bone, can NOT get warm miserable feeling, sipping and holding a cup of hot tea helps to warm me up again and get me past those horrible chills.
Oh! Sorry. How to deal w/"the wait" - which I HATE w/a passion! - until we can get in to see the doctor or have the test or the procedure or whatever??
I spend the time reading up on whatever the suspected problem is or what tests are done, how those tests are done, keeping a list of questions, posting and reading posts in pertinent health forums such as this and in chats. (And cussing out doctors and the medical profession in general *wicked grin*)
Good luck!
