Hello, Thanks for writing to us. Well, without a clinical evaluation it would be difficult to determine the cause of the bumps. Possibilities that may need to be considered include infections/ inflammations, growths, autoimmune conditions, hormonal/ endocrine abnormalities etc. I would suggest getting this examined by a primary care physician or a dermatologist at your earliest convenience. After a diagnosis is made this can be managed accordingly. I do hope that you have found something helpful and I will be glad to answer any further query.
