<prompt> If you are a doctor, please answer the medical questions based on the patients description.I was showering the other morning and my thumb locked up and would not move. It wasn t like a catch or a joint locking up. My arms the night before were numb and tingling. I went to the emergency room and they said I had a seizure. They diagnosed this with out even taking my blood pressure etc. I went to a different doctor, that one said it was an anxiety attack. both are wrong. Not sure what caused this. I m thinking maybe neurological . Thinking I should have a MRI . I m a 24 year old female in excellent health, I work out no less then 3 time a week and I eat very healthy.Jacey  <response>: Hi, First, let me tell you that blood pressure reading is not required for the diagnosis of seizure. In my opinion, thumb getting locked up was probably Trigger thumb- a condition where swelling at the base of thumb locks up the thumb in flexion. For this, I would suggest painkillers and if it persists then probably you may need a local steroid injection. Hope I have answered your query. Let me know if I can assist you further.
