Thanks for your answers.
I called them stuck pixels (not hot pixels) because they are there all the time, including taking dark frames. They trail due to the AZ mount trying to keep centered on an object.
I am only using the demo SharpCap atm so I can't use dark/flat subtraction. Once i get my new EQ mount sorted i will upgrade to the full version. This may sort out the problem as ChrisV mentioned.
Originally i could only see 2-3, but now there is 5 or 6 squiggles. This is a little concerning
