I had cryotherapy on Sept. 20 and had the worst headache of my life after only 1 minute and 40 seconds. It started on my left temple side and spread all the way around my head, I was crying and unable to move for 30 minutes. I flew home from Hawaii and have had headaches to date. I am 63 with high cholesterol. My doctor prescribed augmentin in case I had a severe sinus infection but I still have headaches and am congested. I did a slow walk a week ago of 3 miles and at the end of it my head was throbbing so bad on the left temple I had to go to bed. It is not like a migraine and I am not headache prone. The cold treatment triggered something and I have not been the same since. Should I insist on CTscan? My blood work was all normal except my cholesterol and TIBC was high. My sed rate and Creative test were normal along with CBC. My neck also hurts and seems to be stiff.
