Cheryl, you need to work on getting rid of your cold - I know, you never thought of that

Your in a difficult spot since your limited with meds. I can give you some ideas but I'm guessing you have already tried: stretching -as if you don't get enough of that with your job , heat - I know, it's summertime.

I have been know to run air conditioning and have heat on my legs or back. This makes perfect sense to me

That's about all I can think of for the moment. Hope you start feeling better
