Hi i am inquiring about my son, i have took him to dermatologist blood doctors and a blood specialist here in elizabethtown ky and louisville ky but none of them can find an answer to what is going on with him. He has knots all over his head three of them are the size of ping pong balls i would say all together he has 15 knots on his head, they are on his back also, i have been told they are what is called cystic acne but none of the treatments have worked. They are very painful, have foul oder, and he is now getting light headed and having head aches , please help! He has been on interveinious therapy , accutane, he is 19 and no other health problems that we know of. Please help !
