Little ball in my right armpit - under arm

I'm male 43, last friday aug/17 when I was having a bath i noticed a very little ball in my armpit, is not visible but i feel it, it has like .5 cm size or little less, If I tocuh it and put some preasure with my finger I feel a little pain, The left armpit is normal.

I use to have pimples in my right arm (5), do not know know why in my arm, and appears after peanuts eat. It takes like 2 weeks to dissapear and 2 of them only made me a highlighted skin that can not eliminate. This start happening (Pimples) 4 years ago.

Do not have any family historical cancer.

I do not have any other symptom actually I feel very healthy.

I'm nervous thinking that can be other serious issue, any idea or what this can be?

Any comment will be appreciated.

Are these pimples raised on top of the skin?  This sounds like an alergic (allergic) reaction to peanuts.  Blood cancers tend to cause lymph nodes to swell, making them feel more like a marble under the skin.  Have you had peanuts lately?  

Some people also get skin tags under the arms.  Possibly this is what you have.  It's hard to say without being able to see it, but if you're worried about it then maybe you should go see your doctor or a dermatologist.

Is just 1 pimple, and if i put aside my armpit hair can see it, but this one is more likly under my skin, and yes I was eating peanuts last 2 months at night (50grms on thursday and tuesdays) in my master class free time. If I make press I feel this little ball solid and feel little pain, If i do not touch it i do not feel anything.

Blood cancer or lymphoma starts whit this alone symptom or has a combination of others? as i mentioned I do not have any other.

The lymph nodes makes pain if we press them?

To be frankly in all my entire life I do not remeber never on having any swell lymph node, so i do not know how this ones are and feel.

I'm very healthy I use to have colds about 1 every 2 or 3 years, no other disease exepct for my cholesterol and tryglicerid levels that I got on december, doctor said is not a worry because are in the limit but diet and excersive can release them, no worries.

Thanks you for your prompt answer.

When you say pimple, do you mean acne?  Sorry if this sounds gross, but does it look puss filled?  Or, does it look and feel like a BB under the skin?

Lymph nodes typically resemble a bean in shape and in size when not enlarged.  What you have doesn't sound like a lymph node.  Also, enlarged lymph nodes don't usually hurt if they are cancerous.  

Blood cancers usually start out with swollen nodes and then can progress to other symptoms like fevers, night sweats and extreme weight loss.  

I don't think you have too much to worry about, but like I said before, it might be a good idea to see your doctor to help put your mind at ease.

Sorry, it does not have puss, pimple was not the right name, I would say little and solid ball (.5 cms) under my skin.

In my arm, are really pimples with puss (acne), but this one  in my armpit (under my arm) is just the little ball, it hurts when i press it.

I do not know what BB is, can you explain?

If I need to see a doctor, what kind of specialist do you recomend?

[Mochadelicious]

Sorry...a BB:  the small, hard balls used in a BB gun. :-)

I would start out with your regular family practitioner.  If they think it's something more to be concerned about, they may refer you to a specialist.

Yes my little ball is and feel like a BB and is under the skin, but can see it putting aside the hair. After removing the hair i noticed a very soft grey color in the area where the ball is located.

Size after 5 days is still the same, pain is still at that area.

Just to clarify, this small ball, that is not growing after 5 days, is solid, under the skin and cause pain after putting preasure and not other symptoms in your experience what do you think that can be?

I'm back from doctor, thanks god is just a benign cyst, he recomend me ALIST for 3 days, Betnovate cream (Bethametasone) both anti-inflamatory, adekon (A & B vitamins) and VARIDASA antinflamatory.

I found this doctor with speciality in dermathology, internist and immunology

It is better to go to a doctor, I was thinking in cancer...

[Mochadelicious]

Good to hear Roberto!  I'm happy you went to the doctor and found out it was just a cyst.  Lumps under the arm can be scary, but you did the right thing and had it checked out.

Take care.
