Why does this bump on my right thump keep coming back?

Doctor's Answers 1

Hi,

It appears you have a digital myxoid cyst. The primary cause is a degenerative joint beneath the cyst (in this case the distal interphalangeal joint of the finger). The degenerative joint allows the lubricative gel within the joint to leak and track upwards to the skin where it appears as a dome-shaped translucent swelling.

Treatment requires this “track” or connection between the affected join to the skin to be sealed. A Specialist Hand Surgeon will probably be the best doctor to treat your condition.

Thanks for the very helpful picture. Your condition is typical of moderate to severe acne, due to the presence of active pimples, acne scars and comedones (or blackheads). The dark coloured, bigger lumps that you described is an infected cyst – the reason why it’s tender, swollen and dark coloured, is because your body mounts an inflammatory response to the clogged pores and trapped bacteria; similar to how your other pimples are formed.

Why does my knee have small dots on it compared to other people's knees? (Photo)

Hi, From the photo, you may have a benign skin condition called “lichen spinulosus”. The cause is not known and it is not contagious. The condition is harmless. Moisturizers and topical retinoids may help improve the appearance. Do see a doctor if the condition really bothers you and if you wish for some prescription creams to help improve it.
