Need to examine: It is not feasible to provide a meaningful opinion without taking additional history, and physical examination, however, it does not appear to be a serious issue. You may watch and wait. If the lesion gets bitter, it ulcerates, or discharge develops or more lesions appear, see a doctor.
For good health - Have a diet rich in fresh vegetables, fruits, whole grains, milk and milk products, nuts, beans, legumes, lentils and small amounts of lean meats. Avoid saturated fats. Drink enough water daily, so that your urine is mostly colorless. Exercise at least 150 minutes/week and increase the intensity of exercise gradually. Do not use tobacco, alcohol, weed or street drugs in any form.
Practice safe sex, if you have sex.

Bruise Or Contusion (Definition)

Bruises, or ecchymoses, are discolorations and tenderness of the skin or mucous membranes due to the leakage of blood from an injured blood vessel into the surrounding tissues.

Excruciating pain by underarm (under skin). Can't recall any bruises/falls whatsoever. (recently waxed) causes?

Cysts vs abscess vs: You may have an infected cyst, an abscess or just an imbedded hair follicle. You may try a common pain reliever but I advise a face to face doctor visit to see if you need a minor surgical procedure to open lesion.

Bruising: A single small bruise is usually of no consequence. Leaning on a bump or bar or hard object can cause a bruise that went unnoticed. Some medications such as aspirin or ibuprofen can make it easier to bruise. If there are ongoing new bruises please discuss with your doctor.

What would cause severe itching under armpits and bruising around the diameter of the armpit?

Allergy?: If you have a rash, I would consider an allergy...Bruising is from scratching...Stop deodorant for a week, use Hydrocortisone and see what happens. If no relief, see a dermatologist.

Bruise? Trauma: Have you had any trauma? Do you paly with your boyfriend? Have you fallen. I am not sure this is important but would be good to know the cause. Sometimes a vein will rupture spontaneously. Time should resolve this problem.

I have underArm bruises with on and off rashes, size 36K breasts and try to wear fitting bras and most times I do not wear a bra at home, causes?

I have underArm bruises with on and off rashes, size 36K breasts and try to wear fitting bras and most times I do not wear a bra at home, causes?

Allergy?: Perhaps the rashes are due to an allergy? I would try a different deodorant. Liquid washing products and clothes drying additives can also be a source of allergic sources. The bruises might be due to small size bra. Google bra fitting and they tell you how to measure and calculate fit. If bra pinches it could possibly bruise the skin. Hope these ideas help.

Evaluate: Hard to say. Could be many causes including the breast (eg breast cancer, infection, etc), chest wall, lungs, or heart. Get a physician evaluation with a history, physical exam, and whatever testing is needed.

I have about a large pea sized tender node in armpit life jacket strap may have rubbed area throughout day is this possible cause? Is it a concern?

Possibly: The armpit is a common location for infections and enlarged lymph nodes. if there is irritation to the area (like a life jacket strap), increased sweating then cooling, it could cause a boil to develop. There are lymph nodes in the armpit also, and if there is a local infection the lymph node may swell. See your Dr if it doesn't start to go away after a week.

L armpit tender radiating down my side and now my arm at the top, found a tiny lump GP evaluating in 2wk? Cause could this be an inf from my glands

Armpit tender: This is most likely coming from a pinched nerve and not from the lump that you are feeling having said that given your age and gender I would suggest a full breast examination and a visit with your doctor as you have planned

Around 1 month ago I felt a lump under armpit in left hand. Now I am not sure it is there but feel oval shaped and it itches and feels tender. Cause?

Lymph nodes: A lymph node is an oval-shaped organ of the lymphatic system, distributed widely throughout the body including the armpit and stomach and linked by lymphatic vessels. Lymph nodes are major sites of B, T, and other immunity cells. Lymph nodes act as filters or traps for foreign particles and are important in the proper functioning of the immune system.

Sharp radiating pain next to armpit from top breast to shoulder. Both sides. Very swollen breasts very tender abd swell fatigue not pregnant. Cause?

Sharp radiating pain next to armpit from top breast to shoulder. Both sides. Very swollen breasts very tender abd swell fatigue not pregnant. Cause?

Be seen: If such symptoms are not from pregnancy, you should get a good history and exam as many causes exist. Obviously new exercise can cause pain in that area. But fatigue and swollen breasts make me consider something with your endocrine/hormone system, or something causing swelling throughout your body like thyroid disease, or liver problems. Medications can do that too.

I'm really worried about the bruise I got on my armpit it looks like a centipede does it mean im being sucked by centipede? Pls help,

Doubt it is: The bleeding in the axils can take many forms. I don't think there is a centipede there at all. You could have your physician clarify

See a doctor: You need to be examined and provide a full detailed history to begin to work this out. Cannot be done long-distance.
