Welcome to 'Ask a Doctor'. Please type your question here...Approximately 2 days ago (10/18/18) I had 2 raw croquettes made primarily from spam and then a normal meal. That was at about 5pm on Oct 18th. I had absolutely nothing else all day; at around 8pm, I started having having back pains and stomach colics. I'ts 10/20/18 and I have back pains, stomach colics and headaches. I'm an 18 year old female around 170 pound and ever since 10/18/18 I've had no solid food.
