hello doctor patta. For the past three days i was having touble pooping and i took align, merilax and align did not help but merilax did. During this time my entire back was hurting from top to bottom all the way up to my neck. I was able to poop today but not my pain has shifted to the right side of my lower/mid back. I also keep shifting from high fever and then no fever. I also have been vomitting alot lately, when i was having the poop problem i onyl vomitted at night once, but since the right side of my back has been hurting i vomit even if i drink water, i have not eaten anything since this pain and if i just drink water or eat something i vomit. what could this be?
