Red painful raised bump on hand. Slowly growing looks like blood blister but feels like splinter in it. Suddenly appeared?

Infection Likely: I would make sure to have this evaluated by your doctor. Given your medical history and the medications you are taking (Humira), you might have a skin infection that will require doctor-directed care. Your immune system is suppressed due to the Humira, (adalimumab) so you are more at risk for getting skin infections. Get it checked out. ...Read more

Nothing, as: Long as there are no signs of infection (increased redness, swelling, warmth, pain). This blood will reabsorb on it's own. Do not try to puncture or "burst" it, as you will increase the chance of introducing infection. If you notice signs of infection, contact her pediatrician immediately. ...Read more

Tiny painless dark oval appeared on hand 3 days ago. Thought it was a blood blister but don't remember an injury. Should I get checked for melanoma?

Bruise: Sounds most like a bruise and sometimes they can pop up without being aware of the injury. You can give it a week or 2 to resolve. I would give it up to a month to resolve. If it doesn't, you could see a doctor, but very unlikely to be melanoma. ...Read more

May have knocked blood blister on man and little bleeding cuts on hands what's the chances I will get hep c or hiv?

Not likely: It is unlikely to get hepatitis c or HIV from brief exposure to blood. Of course it is impossible to get hep c or HIV from a man that does not have the virus in the first place. Hopefully you know this man and can ask him if he has hepatitis or not. Hepatitis b is much more contagious, and there is a vaccine for this, so see your doctor and make sure you are immunized! ...Read more

I have a black spot on my hand but I am not sure if it is a blood blister or a mole it has been there for about one and a half weeks?

I have a black spot on my hand but I am not sure if it is a blood blister or a mole it has been there for about one and a half weeks?

Unclear: Blood blisters are usually painful, and related to pressure or trauma though not infrequently there may be no recollection of a specific event. They can take several weeks to resolve as the blood gets reabsorbed by the body. A mole typically is not painful, and would not change much over a month. So time would likely help answer this question for you. If worse, please have it examined. ...Read more

I have a small raised rash on the back of one hand it itch's and burns, and when drying it with a towel sometimes it looks like tiny blood blisters?

A photo would help: Have you been out in the garden lately and been pricked by a thorn or touched poison ivy? It sounds like an allergic reaction however; we cannot rule out herpetic whitlow which gives the same symptoms burning pain tingling, sometimes swelling. You could have acquired it from another part of your body or someone elses. For now avoid sharing towels as it is contagious. See your doct for diagnosis. ...Read more
