My 18 yr old daughter had a spinal fusion in June, now 7 months later she gets choked when eating?

My 18 yr old daughter had a spinal fusion in June. Two days afterwards she had bilateral swelling in the supraclavical area of neck. They are the size of lg eggs. The size changes daily. Now 7 months later she gets choked when eating and says the areas hurt. We have been to family Dr three times, two different ent’s, an endocrinologist. She has had ultrasound, MRI & been tested for Cushing’s. All of which were negative. Neurosurgeon says not from surgery. We have been told not going to die from it since it’s both sides, that its just fat, andi have noidea but its not normal. Please help my daughter! We are so tired of no answers!
