I'm on both, also (185 synthroid, 20 cytomel for thyroid; 5 prednisone) with no "ill" effects yet. I definitely can breath better and the joint inflamation is down now, since I've been on the steroid regularly. Your thyroid can affect blood pressure & blood sugar levels, too...
As to the muscle cramps you all are talking about. They come from the low calcium levels in your blood. If your thyroid is under functioning, chances are so is your parathyroid. That controls the calcium levels in the blood. That causes pain and cramping in your muscles. If your levels get too low you could end up in muscle spasm that are as severe as a seizure. Vitamin D also comes in here somewhere, I haven't figured that one out yet. Find a good endocrinologist. I've been dealing with this since I was 27. It's like the Lupus; it's not fun. I missed my synthyroid for over a week due to issues with my endo's staff. I'm exhausted, no strength at all. It will take me weeks to get my energy and strength going again.

I'd forgotten about that calcium/magnesium relationship. The vitamin D "leaches" somehow or other, and it helps in the absorbtion of other minerals, etc. to be up to level or above with it. You need it for other things, too (?? blank brain today), and can't get out in the sun to make your own, so supplements it is...
Also - I have been going through thyroid testing this year too and started a thread with some information for others who are also overwhelmed by all the thyroid info out there.
As long as this body works, I am going to enjoy life to the fullest for each second of every moment that I can.
