I have noticed lately that my otherwise flat/normal nail beds on hands have developed verticle ridges. I thought it was due to aging. Now the front of the nail beds seems to be raised/bulged. This has occured on all fingers. I'm a 28 year old female, delivered baby 4 months ago, had a c-section, have kidney stones and taking lithotripsy treatment currently. Please advise if I should be worried of any underlying problem. Pics for reference. It may not be clear in the pic but definitely noticable when seen directly.
