Waking up with a start, dropping feeling

Hi 

I am not medically trained but I don’t think it’s anything to do with your treatment . 

Feeling like you are falling and waking up with a jerk is a common, harmless phenomenon called a hypnic jerk  or sleep start. It’s about your muscles being relaxed as you awaken. 

hope that helps a bit but always check with your cancer team if your concerned

Hi Pieman,

I have never seen it mentioned on the forum before as a side effect of RT or HT, but if it's worrying you then you can always raise it with your team for a bit of reassurance.

Funnily enough, it's something that has happened to me on occasion for as long as I can remember, long before any treatment.  I did read up about it once & if I remember correctly, it's something that can happen when you move between light sleep to deep sleep.  It is a really weird sensation.

Best Wishes
