Seriously people stop it!
There is one common thing that each and every person here shares. He or she feels some symptoms, pain in the 0104, pinky twitching, brain fog, rain or some other weather type thing, perceived weakness, true weakness, some in between weakness, occasional nausea, full time nausea...you get the point, and the first impulse is to, guess what, google.
Then, google gives you the most common diseases for your symptoms - ALS, MS, Colon cancer, Stomach cancer, Lung cancer, Pancreatic cancer...
And finally, when you are all freaked out, panic gonna die tomorrow mode, you come to this forum, or forum of similar type to get reassurance and to calm yourself down.
I know this is the process because I was guilty of doing it for so long.
My suggestion for you is this : You get the symptom (any symptom), first, before going into full panic mode, come here, on this forum and post it. Let other people tell you their opinion, rational opinion without anxiety involved. And if your symptoms sound severe, people here will tell you to see doctor, or if you are experiencing severe pain nausea etc. go see a doctor yourself. But please skip google, it's the worst doctor on this planet. It didn't help you in the past, and it certainly won't help you in the future.
