Why is there a brown line of discoloration on/in some of my nails? From bottom to top

Could be many things: Lines of pigment in the nails are often seen in individuals who have darker pigmentation, such as african american or darker latin individuals. Discoloration can also be due to trauma, or in less frequent cases, from a form of skin cancer called melanoma. I suggest you have a dermatologist (if on hands or feet) or podiatrist (if on the foot), take a look and evaluate it to rule out melanoma. ...Read more

Swelling around nail, yellow discloroation 26 yr old male, (if relevant: total thyroidectomy (papillary carcinoma) jan 2011). Swelling around the tip of finger to first joint of right ring finger. Yellow discoloration on cuticle and further around nail. P

Nail : Nail bed infections are called paronychia (try pronouncing that one) and they happen when the skin and soft tissue next to the nail bed get infected from a break in the skin. They are usually caused by staph and strep which are common skin contaminants. When they stay localized to the nail bed then hot soaks and some over the counter antibiotic ointment works well. However when you start to feel pain in the arm and up into the lymph nodes under the arm , then physicians worry about "blood poisoning" or spread of the bacterial infection from the nail bed into the lymph system. So that's a doctor visit and i wouldn't wait too long to be seen. Doubt it's related to your thyroid cancer however. ...Read more
