Just got back from the ER. I am in horrible pain from something that is only 3 mm in size. It just hit this evening out of the blue! I have never had this type of problem. I hope it passes soon as the pain is just astounding. I don't yell or scream in pain very often. I did with this. I still may as it passes. asses. At least the doctor gave me a prescription for pain medications for a day or two until it passes. If any of you have ever gone through this misery, I truly, deeply sorry.
