Here's some recommendations:
1) when in doubt, see a vet!
2) if your day temps are at a constant 90, that's too hot. You must provide a gradient where your low end temps are around 80 and the warm end at around 85-88 with a SMALL, LOCALIZED basking area that reaches 90-92 deg F. Night temps can run from 80 cool side to low 80's warm side. Your hot temps could prove fatal in the long run.
3) BOOST your humidity levels; they should be at the 60-75% mark. If this is a problem, construct a humidity box w/a plastic food storage container with a hole cut in the lid and the box filled with 2-3" of dampened spaghnum moss. Many snakes will actively seek these areas out to hide in. Daily mistings with lukewarm water will also help.
4) What type of bedding do you use? If the snake ingested some wood mulch or some other particulate-like matter, that could be lodged inside the snake....this is a medical emergency and could require surgery. I personally would recommend keeping this snake on newspaper.
5) Soaking in a shallow tub of lukewarm water (78 deg F.) for around 30 minutes could help quite a bit.
6) Hold off on feeding until you rectify this problem. Continuing to feed with an already clogged system will only make matters worse and could lead to septicemia.
7) There could be other problems causing this which is why I recommend seeing a vet and doing a full fecal and blood work up....yes, it costs money but that's your responsibility.
Bottom line is that if the snake is not acting right, get it to a vet right away. Delaying treatment/surgery will only result in a dead snake.
