Hello! I Have Had Severe Stomach Cramps For Years, And

Hello!
I have had severe stomach cramps for years, and because of this I had to lay down in bed all day, the pain also causes me to be absent in school sometime. I've recently been taking Buscopan everytime I feel severe stomach pain. My stomach cramps isn't always that painful, sometimes the pain is tolerable (say 2-3 times a year, if I'm lucky). But now, I have noticed that my stomach cramps completely disappeared. Its been 5 months now. There is still pressure but its barely noticeable. Is this normal?
