After a time away from Spring Forest Qigong exploring other health avenues I have come back to it with renewed passion. I have been trying to clear my blockages in both knees and lower back for some 8.5 years now but not really getting very far despite some gargantuan efforts! My question to you all is this: Whilst practising the Level 1 exercises my knees become so painful I have to sit down and continue doing the exercises seated. I manage to then stand again for the final 2 exercises and the harvesting of Qi. The pain I normally experience in day to day life from my knees and back is around 5 out of 10 but now is up to 8/9 and is making life pretty tough. I know that Chunyi says that the pain may increase for a while as the energy pushes the blockage but it is hard to even stand now. Should I just continue doing the exercises seated and then the Small Universe or just back off for a while?
