What you're describing — those sudden jerks in your left leg and left hand — sounds like it could be myoclonic seizures. These are brief, sudden muscle jerks that can happen on one side of the body and are a recognized part of epilepsy.

The timing is also worth noting. Myoclonic jerks often happen shortly after waking up, which lines up with your experience of having a seizure not long after your alarm went off. As for whether they can be a warning sign — yes, they can be. For some people, myoclonic jerks act as a kind of early signal that a larger seizure may follow, especially around waking hours. It's not guaranteed, but the pattern you're describing is something worth paying close attention to.

Here's what's helpful to track and share with your neurologist:

- When the jerks happen (morning, evening, random times)
- How often they occur
- Which body parts are affected (you've already noticed left leg and hand — great observation!)
- Whether a bigger seizure follows and how soon after

This kind of detail can really help your doctor fine-tune your treatment plan. If the jerks are becoming more frequent or are consistently followed by seizures, that's definitely a conversation to have with your care team sooner rather than later.
