Hello everyone. I am new here! Please bare with me as this will be a long post, but hopefully you guys could enlighten me as to whether this prolonged mystery illness I have could in fact be Fibromyalgia. To begin I am a formerly healthy 30 year old man, 5'11'' and 150ish lbs. It all started in late December of last year when I began having night sweats and chills during the day. When it first began, I immediately went to the doctor. Since my cervical lymph nodes were also swollen, she performed a neck CT scan, CBC, and metabolic panel. All normal. I was uneased by this, and so I also began developing bad anxiety and depression. My symptoms continued until February when my resting heart rate suddenly began staying around 100 bpm. Went to a cardiologist and diagnosed with sinus tachycardia. Well then I began noticing darker colored stools and weight loss... went to a gasteroenterologist, and had a tiny peptic ulcer. March comes around and I begin experiencing dehabilitating fatigue. Also, I begin having urinary symptoms. Occasional flank pain, nocturia, foamy urine, and cloudy urine. When all of this first began, I thought it was cancer related due to the sweats, chills, lymph nodes, and eventual weight loss. Since March, I've been convinced it's entirely kidney related, with my current theory leaning towards a vicious kidney infection. Here are my current symptoms: Occasional headaches Tinnitus especially at night Daytime bruxism Seems my vision is "different" Mental confusion Bad fatigue No appetite at all Nausea about once or twice a week Hair growth has slowed Nails seem pitted Restless feet during day Occasional muscle twitching Occasional insomnia My muscles seemed to have atrophied. For example, my calves and thighs are doughy. When I flex them, they get hard, though. Skin is very dry/scaly/cracklely Muscle cramps occasionally, especially legs Hand Tremor - varies from none to mild Muscle weakness Loss of libido Strange skin manifestation on back Cloudy urine / foamy Nocturia seems to have subsided. Occasional dizziness Anxiety Depression Uneasiness To me, everything points to uremia and a kidney infection. The problem is I have seen 2 Nephrologists, urologist, and a rheumatologist. All of my labs come back normal. The only thing that doesn't is sometimes my MCV is a bit low, blood sugar a little high, vitamin d a bit low and my urinalysis will sometimes show mucus, hyaline casts and micro rbc. So I am suffering from some undiagnosed condition, believe it is kidney related but has alluded lab results. The more I read about Fibromyalgia, the more I think it is possible. I guess the main doubt about my own theory is the fact that I am still alive. It would seem if I had uremia, which manifest went kidney function is less than 5-10%, I'd be dead considering the majority of those symptoms began in March. I keep thinking I'm dying and I'll be dead in x time, but I always make it to x. Thus now I am open to other possibilities. I know Fibromyalgia can cause fatigue, skin, urinary, mental and gastrointestinal symptoms. Perhaps it is indeed somatic in nature. Do any of you experience the severity of my mentioned synptoms? I'd be interested to know. By the way, I am seeing a psychologist as well as to not completely rule out mental aspects. My biggest fear is my muscle weakness/atrophy which theoretically could be from disuse. Thanks!
