I'm a 27 year old male, and have been having an increasing number of symptoms over the last 3 months. I don't know what I should do next or even if my symptoms are all caused by the same thing.
Initially I had what felt like bad indigestion after eating lunch, with pain at the top of my stomach and in the left side of my chest (particularly in a small spot just inside and above my left nipple). I could feel my pulse on the left side of my chest just in the area that was hurting. I also felt like I had gas in my stomach and kept belching for about 24 hours. Those symptoms have at various times since then gotten mostly but not entirely better and then gotten worse again.
About 1.5 weeks after the initial symptoms started, I had pain and muscle spasms starting in one spot on the right upper part of my back. The pain spread through my right shoulder and into my neck, and then into the right side of my back and into my right upper arm. After a few days, the pain improved, but it has never entirely gone away. For a few weeks, I had little pain in my back and neck, but had pain in my upper arms, shoulders, and armpits of both arms (though not each spot all the time).
About 2-3 weeks after the back pain had started, I had what started as a mild headache on one side of my head, but then developed into pain around and behind my eyes, as well as blurred vision. After a couple days, I also started having pain in the surface of my eyes and sometimes red spots or blood vessles showing up. I also had a mild sense of being off balance. For one day soon after the eye pain started, I had a particularly bad headache, and have had milder headaches since then. A couple weeks later, the sense of being off balance was temporarily worse, but still not so bad that I was falling over or anything like that. I also started seeing spots or streaks of light move across my vision, which were frequent for two days and have since grown gradually less frequent. The pain behind and around my eyes continued for a few weeks, and has since recurred on occasion (most recently 2 days ago). The pain in the surface of my eyes and blurred vision has still occured frequently since then, but not all the time. My jaws have been popping a lot since the eye pain started, but they have popped for years so I don't know if that could be contributing to my symptoms.
I have also had sore or stiff fingers and toes, as well as pain in my chest where either along the breastbone or where my ribs meet the breastbone. I had a couple days where I felt very tired and weak, with my fingers and toes particularly feeling cold and sore and my upper arms particularly feeling weak. During the period of time when I was feeling particularly weak, I also had symptoms of a mild cold (mild nasal congestion, a mildly sore throat), and I have again had symptoms of a mild cold this past week, but in general I haven't had symptoms of a cold during the rest of the time I have been having these other symptoms. The only times I had any fever was a fever of 99.4 today and a fever of 99.3 when the back pain first started. The rest of the time, I have had no fever at all.
I have gotten the following tests, none of which have lead to a diagnosis:
I initially had an EKG when I was having chest pain, which a doctor thought might indicate pericarditis. However, I followed up with a cardiologist and got another EKG and an echocardiogram, which he said were normal (he said I had early repolarization on the EKG, which was mistaken for signs of pericarditis). An x-ray of my chest was also normal.
I later got x-rays on my back, neck, shoulders, and my chest again after I had been having pain in my back, neck, and shoulders, but all of them were normal.
I got first a CT and then an MRI of my brain after I started feeling off-balance and having headaches, but they were both totally normal.
I had an eye exam from an ophthalmologist when I started having pain around my eyes, and had another eye exam with a visual field test after I had been seeing spots and streaks, but both times he found nothing wrong with my eyes or optic nerves.
I had an ultrasound of my abdomen after the pain at the top of my stomach got worse again, but it was totally normal.
I saw a neurologist and had a EEG, an MRI of my neck, an EMG of my arms, and a nerve conduction study of my arms, all of which were normal except to indicate a slightly pinched nerve in my left arm (I think due to using the computer or playing video games).
I had a blood test for Lyme disease, which was negative, and a blood test for Epstein-Barr, which indicated I have had it at some point but don't currently have an acute infection. I have gotten numerous other blood tests, including a complete blood count (twice) and a comprehensive metabolic panel (twice), as well an antinuclear antibodies test, rheumatoid arthritic factor test, sedimentation rate test, creatine kinase test, C-reactive protein test, and I think some other blood tests as well. All of those were normal (one of my cholesterol numbers was a little bad, and my blood sugar was just slightly above the reference range, but I wasn't fasting for the tests). I also got a stool test for H. Pylori bacteria, but it was negative.
I had slightly high blood pressure a few times (140s over something in the 80s, I forget the exact numbers), but for the last few weeks it has been normal (usually something in the 120s over something in the 70s). However, today it was up a little again (something in the 130s over something in the 80s).
Anyway, I have no idea what to do next. My doctor has basically ruled out all the things he thought might be causing my symptoms, and I don't know who to see next. I'm considering seeing a rheumatologist (even though the blood tests for things like rheumatoid arthritis or lupus came back normal), or a gastroenterologist (since I keep having pain or discomfort at the top of my stomach). I was also thinking maybe I should see the cardiologist again, since I only saw him when the initial symptoms first started 3 months ago, and have continued having chest pain since then. If anyone has had anything like this or could at least recommend who I should see next, I would really appreciate it.
