Symptoms are back after Parathroidectomy

Im a 28 yr old male. I was diagnosed with Parathyroidism in 2003. A MIRP was done and they removed 3 3/4 parathyroid glands. I developed UC sometime during all this. My symptoms have all seem to come back in the past few years. I'm making stones again. ESWL left side 3 days ago for 7mm stone. Aside from the pain and fatigue. I am starting to get headaches that just dont go away. I can hardly remember what I did a few hours ago. Lost around 27lbs in the past month. Onto my third Dr. and noone seems to know whats going on. Anyone else have issues like this after Parathyroidectomy?
