Could it be worms?

I’ve been suffering from IBS for about 4 years. My symptoms are usually linked to my anxiety and PMDD mood swings. Recently however, I’ve noticed a change in symptoms. Instead of my normal nausea, bloating and gassiness I’ve been having sharp, upper stomach pain sporadically (My pain is normally intestinal), and on a couple occasions I’ve been continuously hungry even after eating large amounts of food.
I’ve seen some people in this subreddit discover worms/parasites are the cause of their pain and I’m wondering it it could be the same for me, or some else completely. Any ideas?
