read the above posts...researching how to heal a sebaceous cyst on my left shoulder. dr. said have it surg removed, but I would like to try cleansing etc first. It's about the size of a quarter but has been causing more and more discomfort...have noticed a lot more aches and pains arm going numb and I play guitar for a living...just probably need a cleanse. is there one you recommend and any idea on sebaceous cyst? have read of hot compresses of castor oil as one way to heal cysts. also dmso/sski applied locally. need a miracle. thank you.
