i was feeling so very sick with cns symptoms. i did a session with a rife machine at my friends house. i felt stoned that evening. the next day i felt horrible with severe headache, stiff neck etc. today i feel good. my neck which has been stiff for months feels good. my brain is sooo much better and my heart isnt pounding as much. i would like to keep doing this if it helps. i remember dr. b telling me once that rife machines may use cathode rays to emit the electromagnectic waves and this means there may be radiation. is this true? can anyone tell me if rife is harmful to us?
