Ice can can cause nerve damage. Do not use it at all until RSD is ruled out.

My best explanation of what RSD pain is like for me, is when you stub your toe, and have that intense burning pain for a few seconds? It's like that, but it doesn't go away. It's much worse than post surgical pain (except for the day of surgery.)

Having someone lightly graze the RSD effected area will be more painful than if normal pressure is applied. You can test this by skimming a cotton sheet over the painful area.

If it is RSD, you must get URGENT CARE. You need a new doc for sure, if he believes you might have RSD, you should have a follow up appointment in a week! He's also throwing you on too many new meds at one time...
