Below is an instruction that describes a task. Write a response that appropriately completes the request. ### Instruction: 40M 5'18 160 pounds. Over the past few years, some weird symptoms either developed or got worse. I was lightheaded back in 2018 and a neurologist found nothing wrong with me. Late December, symptoms sent me to the ER with elevated blood pressure, white blood cell counts at 14.5, stomach and intestinal pain, rapid heartbeat, etc. My heart rate and blood pressure rapidly fluctuate. My heart rate varies by at least 20 beats per minute from the base line. So I'm sitting and the base is 70, it will go 72, 75, 78, 80, 82, 85, 87, 90...88, 86, 84, 83, 0, 78, 75, 72, 70 and sometimes do that whole course twice in a minute. I am not known to have ever had Covid and I am presently fully vaccinated, as well.Over the past few years, I've been seen by primary care, neurology, gastroenterology, endocrinology, had head/abdominal scans with nothing noted, saw 3 cardiologists, wore 2 Holters for a month, had lots of blood work and such. Stress Echo via treadmill showed a healthy and strong heart.Diagnosis of Postural Orthostatic Tachycardia Syndrome by primary care, neurology and cardiology. Dysautonomia/autonomic dysfunction got thrown vaguely into the mix, as well. Tilt table test would have been negative for POTS. I didn't faint or have the rapid rise in heart rate. They gave my sublingual nitroglycerin and I fainted within a short time. BP went down to 97/56 and pulse to 40, possibly only because of the nitro. I am lightheaded 24/7. Even just lying on the bed at night, I feel little sharp "zaps" of lightheadedness. I'm familiar with BPPV and it's not that. The POTS no longer applies - I am rarely tachycardic. Also, my blood pressure is now more so low on a daily basis. For instance, earlier today it was 99/57 after a meal that was quite heavy in salt. I seem to always crave salt and can't seem to get enough of it. I am completely exhausted every day, have no energy and my entire body is hyperreflexic.I have hundreds of tiny little red bumps all over my upper and lower back and the backs of my arms. They do not itch. Back in 2020 an EGD showed an inflamed stomach lining with negative biospies. 6 months of Prisolec 40mg twice daily at that time didn't help. He put me back on the 40mg twice daily again. It was after that point that I ended up chasing the POTS/autonomic dysfunction stuff and had not seen the gastro doc since because I later lost my job due to a work injury. I just saw my gastro doc again recently. After reviewing my symptoms, he asked if I have ever seen an allergist. Then when I told him about the horrific lower colon pain that I get at times, constipation on average of 2-3 days at a time due to inflammation preventing a bowel movement, the feeling of inflammation and severe burning/clawing pain for hours even after a bowel movement and such...he feels that I may have something else going on in my colon. He brought up Crohn's and said it was sneaky sometimes. I showed him photos of my pie crust-like tongue that seems to swell at times and I get canker sores in various areas of the mouth and have for a long time. I showed him a photo that looked like I was pregnant - considerable lower colon swelling and abdominal bloating. Also, what makes me think some of my other symptoms like the low blood pressure and such may be related is because when I press on my lower colon area or rub it, my ears immediately ring and at times I get nauseous. There's no way that's a coincidence given how often it happens.I'm always hungry for big meals even after I just ate a big meal recently. I get considerable postprandial hypotension. I haven't worked in 2 years, pending Disability. Gastro doc requested CBC, Comprehensive Metabolic and Thyroid/TSH panels. All within normal range except the thyroid panel:T3 UPTAKE 24 Reference Range: 22-35 %T4 (THYROXINE), TOTAL 10.9 High Reference Range: 4.9-10.5 mcg/dLFREE T4 INDEX (T7) 2.6 Reference Range: 1.4-3.8TSH 2.25 Reference Range: 0.40-4.50 mIU/LThe only flag was the T4 Thyroxine and it's only 0.4mcg/dL higher than the highest normal reference range. All other blood work was fine. This reference range seems normal and also what is 'normal' seems to vary considerably depending on what source you compare it against.Severe burning/clawing sensation in the lower colon just below the navel. Worse at night, but moderate pain 24/7. Full-body malaise, jitteriness and rare spikes in blood pressure with full-body tremors as if freezing cold for 15-20 minutes. I get even more colon pain during this time and at times feel feverish. I have had unexplained blood pooling in my hands and feet since I was a teenager. Heavy nausea immediately after lightly pressing or lightly rubbing the lower colon area below the belly and middle abdomen. No vomiting. Frequent bright yellow or greenish stools with some worm-like mucus in them. No visible bleeding. Upper body jolt-like 'tics' that feel at times as if they are originating from the lower abdominal area and cause my upper body to jump randomly in certain movements. With the lightheadedness, it feels like even when I'm sitting or lying down an djust move one arm or leg, I get a brain "zap" of lightheadedness. What in the world could cause that?I'm trying to get a colonoscopy to see for sure. Due to low income, the Colorectal Cancer Alliance has me on a list for funding for a colonoscopy locally when it becomes available, quoting possibly in February when more programs open.What are my chances of Crohn's/IBD with the above issues going on? Could it also be the cause of my blood pressure and heart rate fluctuations? I'm puzzled at the normal white blood cell counts given that my lower colon was absolutely hurting/inflamed during the blood draw.. ### Response: There's nothing here that suggests IBD, though that doesn't mean you can't have it.It's possible that you have IBD but your symptoms are pretty vague and not classically IBD.
