This past weekend I began feeling constantly like I needed to urinate, even right after I got out of the bathroom. I went to see my doctor today, and they did a round of tests but couldn't find anything wrong with me. My blood sugar level was 88 (well below normal), and a urine sample found no bacteria or blood. I wasn't running a fever either, and have no serious pain on my body. In addition to the frequent urination, I also have dry mouth and feel very bloated (however, I suffer from anxiety disorder and the bloating is probably a side-effect of that). Any ideas?
