I chose Dr. Willen because of his website and the work he does regarding allergies. I have suffered for years with terrible sinuses related to allergies and all that goes along with allergies. I am a year round allergy girl, not the seasonal one either. I suffer all day, everyday. I have spent numerous hours in allergy doctor appointments and several thousand dollars on medicines that just never seen to cut it for me or leave me feeling like I could crash at any minute. I thought well you've tried everything else so might as well give this a shot. I called, made my appointment, had my first treatment and viola its like 30% better. I have my next visit and again remarkable improvement. To date I've had I believe 5 or 6 treatments and I can honestly say that I'm 95% better than the day I started the treatments. I must also say that I suffered from headaches every single day. To what degree they would be, I just couldn't know. I would eat Ibuprofen each day to the tune of about 8 to 12 tablets. I would have a migraine at least three times a month. Since my treatments I've have had one major headache. I no longer eat the tablets either. I was skeptical at first but man am I glad I took the chance. Dr. Willen has given me my life back. I love the outdoors and love working outside and NOW I CAN! I can't say enough good things about this treatment. If you suffer from allergies as I did you will not be sorry you took the chance to try an unconventional approach to allergy treatments. I'm a new woman and I HAVE DR. WILLEN TO THANK FOR THAT! SO THANKS DOC!
