Hi, i was looking for help for a problem of mine: i've just started practising the basics of qi gong, diaphramatic breathing in the specifics, but i have a problem with focusing on the lower dan-tien, basically due to weight loss issues i did a tummy tuck(abdominoplasty) in my stomach and i lost sensitivity in that part of my body, so i have problems feeling the dantien. Is there a way for me to feel it and concentrate into, maybe inside the body? thanks for the help
