2.5 years of palpitations, pain and headaches, scans normal, still symptomatic

Summary

For about 2.5 years they have had palpitations, abdominal pain, constipation, severe headaches and vision problems, plus poor mental health, and wondered whether it could be long COVID. Blood tests, brain and abdominal scans and an MRI defecography were all normal. Two antidepressants and psychotherapy did not help their mood, and they doubted the cause was psychological. They remained symptomatic, awaiting neurology and urodynamics.
