If it's a real bowel obstruction, you would know, the pain is rerally intense, and you could perforate, that is dangerous. I've had 1 that surgery to remove 8ft of disease and obstruction, in small bowel. then I've had resection surgery, that was elective or I would have had OBS. so dr's and myself said yes I needed another foot removed to avoid OBS> but what I get is, I call them gas blockage, nothing goes thru, resected site is inflammed, and it is a blockage, bad cramps, comes in waves, when bad it seems like every 45 seconds. lasts anywhere from 2-12 hr's. I take pain med's, have to. as soon as gas starts to pass, then I know I'll be alright, for me the pain med's can help in breaking up gas. wow, well good luck i hope for you it's just gas type blockage, and not diseaesed gut.
