What causes trigger finger in the thumb?

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

First of all, 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.

I am experincing two sore thumbs, the left has a trigger finger snap to it and hurts the most. I have the problem worst in the morning although it has persisted for weeks now. The pad or little bone at the base between the thumb is the sore spot. I can bend both but the ,eft snaps when i do. Could it be a posture issue? After raking yesterday it hurt less and woked better for a while.

I have trigger finger in my left thumb. 6 weeks of sleeping with a brace have not helped so I am being advised to try a steroid injection in my hand. I had a cancerous kidney removed last may. Will the cortizone affect the remaining kidney?Note that so far I am cancer free.

I had surgery for carpal tunnel about 6 months ago. (I am 56, take no medications, a little overweight but in good health.) Since the surgery one side of my middle finger is extremely sensitive and the muscle in my palm, below pinky finger, at my wrist frequently has pain in it; resting it on the desk while using mouse makes it hurt. I have been told I now have trigger finger in the thumb on that hand and am now having stabbing pains in my wrist and up into my hand and fingers, along with what feels like tendinitis when I move hand or fingers certain ways. I can hold something in my hand and turn wrist slightly and have a pain and lose my grip on what I am holding; or I try to turn a doorknob but can t open the door; or point my finger at my grandaughter and motion for her to come here and it causes pain, I can t put any weight on my hand, like to help push myself up...Is all this coincidental or could it be caused from the surgery? What can I do ?
