Lisa,
questions.. have you had your MRIs done at same place each time? Have you had more than one Dr. opinion? Have you sent info out to House clinic just for the sake of a "free" second opinion from reputable, experienced Drs.?
I found just having that info available to compare to local Dr.s was very helpful ,, even though I would consider going out there,, personal issues dictate I am not really able to at this time,, but their consult was very rewarding and I was able to compare if my Dr suggested the same things.. if you get my drift here,,,,, PLUS if someone is telling you YOU MUST make a decision right NOW,, I would step back from them and get another opinion...
In my experience and most Drs will tell you,, these are slow growing and most all of us have time to think.... some less than others due to size and location,, but yours ,, to me and I am not a Dr by any means,,,,yours seems small and symptoms do not seem intolerable from what you describe... you must be comfortable with your decision whatever it is,, to w&w or move forward and you will know when it is right... I did anyway,, I just could not tolerate the headaches and other symptoms any longer... but try to find other opinions if you can,, the more you input/info you can get from others, Drs included,, the better you will feel about your decision I believe,,
Hope I have not rambled on too much,, but I hate to hear someone rushed into this decision unless there is medical reasons or bad symptoms to warrant it......good luck..
