Hello there.  I can understand your concern.  Im not sure what bobbles even mean. Kindly use a proper term ehich can be understood by all. And also, for understanding skin conditions, seeing them is very important.  So it would be better if you even add a picture of what you are having. Also you could consult with a dermatologist in person for further evaluation and management. Best regards. Dr. Anil kumar jain. Bangalore.
