Too many symptoms at once — anxious about what to check first

I’m dealing with several physical symptoms at the same time and it’s making me really anxious. I don’t know what to get checked first, and I’m worried that if I focus on one thing I might miss the real problem.

Here are the main issues:

1. Pain from my neck to my right shoulder. It comes and goes, but when it happens it can be very intense.
2. General stomach uneasiness most of the time.
3. The most concerning one: pain on both sides of my abdomen. Sometimes it feels like a stabbing knife-type pain.
4. Occasionally I feel pain around the heart area. It’s rare but it happens sometimes.
5. My stomach gets very bloated after eating and digestion feels unclear or uncomfortable.
6. When I rotate my neck, I always hear cracking sounds. There’s also a strange sound from my neck area that I can’t figure out.

Background: I previously had Hepatitis C and completed medication treatment. I’m not sure about my current viral load but it might be low or zero. I was also told I had stage-1 fatty liver back in 2022. My lifestyle has been unhealthy for a while due to workload and I’ve been very inactive.

Honestly, I’m also afraid to go to a doctor because I’m worried they might find something serious.

Has anyone experienced something similar? What kind of tests or checkups should I prioritize first?
