Thanks for choosing health care magic for posting your query.
I have gone through your question in detail and I can understand what you are going through.
especially the ones which have been coiled have a chance of recurrence. Now the headaches
that you are describing could be an onset of another aneurysm. It would be wise to get an MRI
scan. It may not tell you which one is going to bleed but atleast its presence can be certained and treated. You should undergo surgery this time rather than the coiling process.
Hope I am able to answer your concerns.
If you have any further query, I would be glad to help you.
