Apologies for the sideways photo - but it will not load it the right way up!
I have just purchased Cefaly 2 and was using it on the preventative setting for 3 days, before getting a migraine today and using the treatment setting.....so I thought I would share my initial experience for anyone else thinking of purchasing one.
The intensity can be altered - which is a good job as it is quite an odd sensation to get used to. It can feel like vibration, tingling or massage in my experience.....but the worst thing for me is that I get some degree of pain whilst using the device (mostly on the right side of my forehead)
Obviously 3 days is not enough to prevent a migraine (I only had one that ended 4 days ago which was a 5 day event) but I live in hope that this device is going to work.
I tried it on the treatment during migraine setting today and the 10 mins that I managed at lunch time was not too traumatic and did make my migraine subside for the afternoon. I put it back on when I got in from work and oh my it was a horrendous experience! Bearing in mind that the intensity increases as the treatment proceeds (I think its 40 mins for treatment)....about 15mins in I ended up ripping it off my forehead as I could not bear the sensation any longer. It felt like an alien was attached to my forehead trying as hard as it could to suck my brain and eyes out of my head! It was intense and painful.....
I am unable to move my eyes much - especially to look upward when I am using the device. Once I closed my eyes on treatment, I couldn't open them for pain! I don't know if it is normal for it to affect your eyes at all (theres nothing in the literature) but I position the device as shown and I get vibration and tingling in my eyelids and eyes as well as in my forehead - on treatment the sensations go up over the top of my head too.
I am still pretty headache free (it feels like the day after a migraine at the moment) so maybe 40 mins of brain twisting torture is worth annihilating a 3 to 5 day migraine.......only time will tell!
