My name is Angie! I am not sure how to reply on this site so i hope this works! I also have all of the symptoms you have discussed! What you are experiencing are exertional head aches! Without the decompression surgery I am guessing it wont get better only worse! That was exactly what happend to me anyway! I also thought I had a tumor! How scary! The decompression surgery extremely helped the exerional head aches! They completely dissapeared! I do have problems with liquids and choking!!! You are not alone and I wish for you the best of luck! Please research your surgeon! Make sure he has done MANY decompressions!!! I wish you well! Sincerely Angie
