Fingers and Toes tips are red and swollen:

I’m practicing lesser Kan and Li  in the morning and Wu Ji Gong before bed for about 10 months now.  I notice that some of my finger tips and toes are swollen and red. On my left hand my ring finger finger nail is also turning blue. Also, my left hand middle finger finger nail is turning blue. I am aware the each finger and toe correspondes to a meridian that goes to an organ.  I understand that sometimes when I practice long enough I increase the flow going through my system.  Could this be what is happening to me or should I consult a Doctor about this condition. I would appreciate your input on this matter.  Thank you.
