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.
