Take it easy,Keith -'66 Sedan....
Those pecker stickers suck bigtime. I had one about 6 months ago. Thought i was going to die. Felt like someone was scraping my insides out with a claw hammer. I passed it through a paint strainer after 2 day.
Glad your on the mend. As an aside note, did they analyse the stones? A lot of times a diet change becomes necessary to prevent them in the future.
