My mom(50) she took 2 dose of primolut n, is stressed alot. she was having severe head spinning, swollen neck , got high bp 150/90 and ecg is not normal.?

Not sure: Primulotin? Never heard of it; do you mean premarin (conjugated estrogens)? Her situation is multifactoral and complex. The anxiety and headaches can be related if she clinches her teeth at night ( bruxism); if she snores badly could have sleep apnea. Swollen neck, is it big or acutely enlarged? If big and she snores loudly consider a sleep study. Some can do home sleep studies but may need to be evaluated.
