Good evening everyone! This is such a wonderful community, and it's very generous of all of you to give up your time to help. I thank you all in advance for any insight you can offer.
I'm a 23 year old male with average build, and no significant medical history. Past surgeries include removal of gynecomastia on my left breast and wisdom teeth.
Since November, I've been suffering from back pain on my right side--between my upper lumbar area and lower thoracic area. The pain typically occurs a few inches to the right of my spine, several ribs up.
The pain is occasionally felt as tenderness on my right flank, in particular when I'm laying on that side (which I try to avoid), but otherwise is an internal pain that I generally can't reproduce by pressing anywhere.
The pain started as a dull ache, but has recently felt "crisper." I've been having occasional pangs of pain that feel like pinched nerves.
I have also had mild to moderate fatigue that presented at the same time as the pain. I have a harder time waking up in the morning and am lethargic throughout the day. I have occasionally been waking up with slight chills--I'll wake up curled into a ball. A few seconds after I wake up, my temperature seems to return to normal. I have no fever or sweating accompanying the chills.
Finally, over the past few days, I've felt a bit of muscle soreness in my thighs, shins, and forearms. It feels as if I've been punched--charlie horse style--in each of my limbs. This could be unrelated, but I can't think of any exercise or exertion that could have caused it.
I have had a fairly sophisticated work-up.
2 CT scans of the abdomen/pelvis, one with IV contrast - Normal
Colonoscopy - Normal
X-Ray of lumbar spine - Normal
X-Ray of ribs - Normal
Chest X-Ray - Normal
MRI of lumbar and thoracic spine - Normal
Ultrasound of kidneys - Normal
Ultrasound of gallbladder - Normal
Bloodwork (lyme disease, mono spot, Epstein-Barr) - Negative (positive for chronic EBV, because of mono I had 5 years ago)
Thyroid - Normal
CMP - Normal
several CBCs - Normal, except for slightly high Eosinophil percentage (8%), and slightly elevated C-Reactive Protein (0.9 mg/L). My doctor did not believe either was significant. Red and white counts are normal.
So here I am--trying not to worry. The pain is real--and my doctor hasn't been able to diagnose anything. I've been through the gamut of self-diagnoses and would love to have some sort of direction to take from here. At this point, I'm lost!
Thank you in advance for your time. I know everyone must be busy.
