You need to see a doctor right away to figure out what is going on. This could be from fluid in the abdomen which can result from serious conditions such as liver failure and others. I can t explain what the strange feeling in your arms and legs is, but everything suggests some kind of systemic problem that you need to get treated as soon as possible. Recurrent UTIs could be from a suppressed immune system. This can result from liver failure and other problems. Are you having difficultly sleeping because of shortness of breath? Heart failure could cause this and swelling in the abdomen as well. Go to a doctor or urgent care and have them do some tests to figure out what is going on. Hope this helps.
