Hi Precious
I agree with Shawn and its probably best to seek some kind of professional guidance to support your QiGong exercises.
With that being said, we've all experienced our foot or leg falling asleep only to feel the numbness after we get up and start walking around then everything is fine again.
The "pain" your may be experiencing could be the body's way of waking up to the energy so that your cells can be rejuvenated. This only a thought and please contact someone more qualified to answer your question.
In the meantime, having increased confidence in your Qigong exercise can only help as Chunyi teaches, confidence is essential to healing!
All Best
