What's the best way to get rid of hand pain that aches me easily, especially right hand. whenever i write or use the phone it just gets so sore within 5 minutes using?

You should be examined to rule out carpal tunnel syndrome, especially if you have numbness of the thumb and index finger along with the pain. Or you can try a wrist brace (CVS or Rite Aid) at night for a week as a therapeutic trial. You are relatively young for this condition but it still can occur. A hand surgeon will be the best to make the diagnosis and fix the problem.
