Lyme disease possibly? Weird scary symptoms

I'm a 20 year old male, and I've been having worsening symptoms over the last year. It started out a year ago with a tingling/numbness in one area on my back near my shoulder blade. This came and went and I figured it was just a pinched nerve. After a month or two it went away, and I haven't had tingling there since.

However, in January I started having weird symptoms. I'll describe the progression below:

January - March: Limbs would go numb occasionally when sitting indian style or leaning on my arm, etc for any period of time.
May - now:

-Cold water sensation down my legs when walking (worsens when walking in the heat)
-Rain drops sensations all over body
-Numbness and tingling in lower abdomen.
-Stomach pains, pain in lower left abdomen.
-Stools have many white/tan spots. Recently stools have been dark/blackish. They always look soft and are filled with the tiny whiteish globules.
-Pinky and ring fingers on both hands go numb and seem stiff when moved. Also pinky and ring toes on both feet feel weird and not quite there as well. Feels like my hands and feet are losing coordination. I can still move them but it just feels uncomfortable.
-Sharp pains that seem to shoot down my stomach all the way to my sphincter? Hard to describe but they're weird and hurt and feel like they travel from my stomach all the way to my lower intestine or something.
-Dry mouth, dry irritated eyes.
-Little mucus (for my whole life I've had to blow my nose every morning, I guess from allergies or from my family's cats. For some reason ever since all these symptoms started, I've been clearer than ever and have little to no mucus.)
-Little black floaters across my eyes frequently.
-Ringing in ears occasionally, also random ear popping and ear pressure.
-Acid reflux and heart burn.
-Weakness and aches all over, especially in limbs.
-Burning sensations in my heels occasionally.
-Occasional itching in random spots.
-I feel as if I have lost muscle mass, but I could be imagining that maybe. Either way I think I look skinnier than before and have less muscle tone, although I weigh the same (154 pounds).

^^^ most of these symptoms worsen at night, also. the two hours before I sleep and the 2 hours after I wake up are when I feel the weirdest.

I'm probably forgetting something but that's the jist of it. It feels awkward typing and playing guitar now, and semi difficult walking up stairs. I am very worried I will lose my ability to play music : ( playing guitar and piano feels awkward to my hands now.

Brain MRI came back normal. I then went to a neurologist, she ordered a Cervical and Thoracic spine MRI. Those were normal. She then ordered a bunch of blood tests that checked for Sjograns, sedimentation rate, HIV/AIDS, Hepatitis C, and a couple other things I don't remember, but all came back clear. CBC was good, B12 good, no anemia. Now my neurologist is saying Lyme disease test is the next step, although I don't have a rash and can't recall a tick bite anywhere.

Does anyone have any idea what this is? I'm so scared and feel like my body is falling apart. I don't want to lose my ability to play music and I just want some answers/help.

hi tyler,
your story is also very similar to my own. i was actually studying abroad in europe (im 22 now) a few years ago when i first got symptoms- it all started with a tingling sensation on my right side of my head and cheek. then i got prickly feelings in the soles of my feet, abnormal weakness feelings in my arms and legs (almost like my brain wasnt sending the correct signals to the rest of my body), fatigue, random pains, joint cracking/crunching, head pressure..... the list could go on for quite awhile. i got super freaked out and actually ended up coming home a couple weeks early from my program bc to seek medical attention.

i also had both a brain and cervical spine mri (which showed nothing very significant that the neurologist believed was causing my symptoms). i was told it was all in my head. ive seen almost every specialist i can think of in the past year and a half and most tests ive had done are negative! ive had negative ELISA tests for lyme, but then a positive one through Igenex. i saw numerous llmds in the past year and was on and off antibiotics. now im trying a more natural route. i still dont have a definitive diagnosis (different doctors argue different things, chronic lyme is very controversial), but i think the most important thing is to find doctors who you trust. and definitely get tested for lyme, many people dont remember a tick bite, never got a rash, and are still infected.

honestly, it was really hard for me being thrown from doctor to doctor and not knowing what was wrong with me! it's so scary, especially at our age when all of our friends are healthy! but one thing ive realized over the past year is to keep fighting for a diagnosis, change your lifestyle so that your body can fight off whatever illness you may have (eat healthier, drink more water, make sure you are getting enough sleep), and try to think healthy thoughts. sounds weird, but not dwelling on my symptoms has made me feel better. i used to be on my computer a lot looking things up all the time (made me more educated on the disease which is good!!) but i was further from reality. now i try to just live my life normally and realize that all of the negative mris, blood tests, xrays are good signs! it means some things are working right! lol

definitely get tested for lyme! hope you get answers soon!
