Information (not necessarily directed at you, just for everyone):
Tourettes is not necessarily a severe form of a tic disorder. All it means that someone has had at least 2 motor tics and at least 1 vocal tic for 12 months or more, though not necessarily at the same time.
whereas a tic disorder, is usually diagnosed when someone just has motor tics or just vocal tics.
Tourretes vs a tic disorder diagnosis does not indicate severity. Someone with just motor tics, may have much more frequent and violent tics than someone with Tourette’s who has motor and vocal tics. And the severity can vary over time, so someone may have 4 months of more severe tics and then 2 months of less severe tics, all these times vary.
also, op, you say there are spans of time with no tics at all. Not to worry you in any way but there are many tics that are not ‘visible’ or very subtle; ie clenching of particular muscles, so could be in the toes, or the wrist or pretty much anything. Equally there may not be any at all for spans. I believe for it to be Tourette’s the tics must be present for more than a year with no break of more than 3 months at a time.
So could be transient tics, that are there for a bit and go and then after a while another appears again, and the cycle continues. Transient tics do not necessarily mean they will develop into Tourette’s or another tic disorder, but equally it could be the start of Tourette’s or another tic disorder. Often Tourette’s starts slowly around the ages 2-14 but average ish of about 6 years old. It can also come on suddenly.
i would get a gp appointment maybe if you haven’t already, and monitor at the same time. It’s often recommended to film the tics to show to the doctor, as a lot of the time doctors can be very dismissive of diagnosed tics, let alone undiagnosed or potential tics.
