This all started about 10 days ago when I had some eye issues. It felt they were darting back and forth and I couldn’t control them. That lasted for the afternoon then I was back to normal after sleeping 

I felt a little off last week, I kept googling a bunch of symptoms and coming up with the worst results: brain tumor, MS, kidney cancer etc. 

Some of my symptoms are tingling in the right hand and right foot. Sometimes tingling in left foot also. 

Some lower back pain in left side and also some pain in front left abdomen 

I went to the walk in clinic last Friday and the doctor said nothing to worry probably a pinched nerve on the right side. 

This kind of made sense as when I woke up Saturday I had tension headache on right side that mostly went away after getting a massage on it. 

Saturday was good day. Hung out with friends all night and had no issues or symptoms. 

Fast forward Sunday night as I’m falling asleep I start thinking of the worst again. This gets my heart racing and I manage to calm down and go to bed. 

Monday during day same issues, thinking of the worst and then I decided to go to ER Monday night. Doctor examined me explained he sees nothing that would indicate it’s a heart issue based on everything I’ve told him. He listened to my heart, had my squeeze his hands after describing the tingling. Essentially says I’m all OK. 

Yesterday, during day I have some chills and kinda tired as I was at ER until 2 am. I also had some nausea that went away later in the day. 

I played tennis last night for 2 hours with no issues. My coordination was very good, no issues getting tired etc. 

I did have trouble focusing as I kept thinking of the worst. 

Went to bed last night. Woke up 1.5 hours later with heart racing. Eventually calmed myself down in an hour and fell back asleep. Woke up another hour after heart racing and sweating. 

Managed to calm myself down and sleep for about 4 hours. 

Physically today I feel OK some pain in front left abdomen. 

But I’m extremely worried this could be something more serious. 

What should I do? Am I just stressing over all of this? Any insight is much appreciated.
