I am a fairly healthy 37 year old male. I used to keep myself in really good shape, lifted weights a lot, etc. Then in my 30's, my energy started declining considerably. A couple of years ago, I had a sleep study that showed I might have a mild to moderate sleep condition. However, a little over a week ago my family got severely ill with something that swept through the household. One family member got violent vomiting/diarrhea at the same time for about a day and a half. Another got moderate diarrhea. Neither had GI symptoms past their sickness time. I got diarrhea for about 1.5 days and probably went to the bathroom at least 30 times during that time. It was dark, liquid/tarry-like diarrhea. Apparently Pepto Bismol (which we took a good bit of during that time) can cause that dark stool. Some medicines, drinks, etc., can also cause it. After a few days, mine went away. However, I have had lingering symptoms where my lower stomach below the navel hurt for days. Hurt as in...I couldn't sleep one night it hurt so bad. I went to the ER. They did some blood work, took a urine sample and also sent me for a CT scan with contrast of my abdominal and bladder area. The ER doc came back and vaguely mentioned that they saw a little thickening of the bladder wall for some reason. They sent me home with 500mg Ciprofloxacin twice a day for 5 days "in case I had some kind of infection" (which they didn't think I had). They basically told me to see a GI doc. When I bend over, I feel like a "folding" sensation around my bladder, like it is stiffer or something. My urine is normal/clear. I have been over the official stomach bug for over a week now, but I still have some diarrhea about once a day. Some days it is more normal and others it isn't. I believe I may have had Gastroenteritis. In addition to the antibiotics, I'm taking a probiotic pill once per day. Sometimes I feel like my abdomen area is "pulsing" at night or something if I lie on my stomach while sleeping. There isn't really much or any pain from the bladder area most of the time. Sometimes it feels a little sensitive or slightly painful if I press on it. Sometimes I have frequent urination, but again, it is clear like water. I do drink a lot of water.
What would have caused this to come out of nowhere and what could it be? I have Cigna "critical care coverage" for stuff like cancer diagnosis and such. However, my official health insurance sign-up isn't until March and it kicks in April 1. I've already spent a few thousand at hospital ERs. They claim it is "anxiety" causing me to have rapid heart beat/sometimes elevated blood pressure. I get random "panic attacks" out of nowhere, for no reason. I just started getting those a couple of months ago. GP doc worked me over for every kind of blood test imaginable. Nothing. ER did the same. Nothing. I've had an MRI of my organs. Only 5 insignificant cysts (said to be commonly found on/in the liver by accident when scanning for some other problem) showed up on the MRI. Adrenal glands and other organs look fine. Sometimes if I press on my bladder/lower stomach, I find that I start getting some kind of odd "panic attack" for an unknown reason. I woke up after being asleep for an hour the other night and had a very severe episode that I do believe was anxiety-related. I do not dispute the possibility of anxiety; my issue is that in 37 years, I've never had panic attacks. Ever. They came out of nowhere over the past couple of months and then I got hit with this stomach bug. Now I seem to have bladder issues and diarrhea with a dull ache/pressure in the bladder sometimes. Some days I urinate more frequently and other days I don't. I can't accept their diagnosis that this physical problem is "anxiety" related only. Some days my GI tract seems really upset/out of balance after I eat. When I lie down, my stomach gurgles and bubbles a lot. No history of any GI issues, no history of heartburn or any digestive issues.
