I've found a small pea sized lump under my left armpit, that is painless and is moveable. Also my glands are also always swollen like big hard lumps.

Seen a Doctor lately: If your lymph glands are enlarged and growing bigger, you need to have them checked by your physician. Lymph nodes do not enlarge unless you have either Infection or Cancer in the lymph glands. So go seek medical evaluation and a physical examination by a doctor, soon. ...Read more

Abcess.: Sounds like you have a small abcess. Pain may be relieved by incision although it is by no means necessary. May use hot compresses several times a day until this "points" and ruptures on its own. The fact that pain is bad indicates that may be soon. It is remotely possible that this is a lymph node that has been very stimulated. Same treatment. See someone if not improving. ...Read more

Mosquito bites: Mosquito bites would be unusual in that area. This is more likely to be an infected hair follicle, especially if you shave. If it worsens, see your pcp for an examination. ...Read more

I"m on day 4 of period. I feel a very small lump in my left atm below my armpit. 4 mnths ago i felt it but it disappeared i think. What is cause?

Lymph node: Probably has nothing to do with your period. Go see your doc to make sure nothing else is wrong. Probably it's an enlarged lymph node. There are many causes of this. ...Read more

I have a painful lump below my left armpit and two small pea sized lumps in my left breast that went away 1 month ago but are now back. What are they?

Check with Doc: Breast masses are common. Most of the time they are benign. They should always be checked out with your doctor. The evaluation may involve a mammogram and an ultrasound as well as an examination. The findings that you described are commonly associated with cysts and can be affected by caffeine and also by shaving with lymph node changes in the breast or armpit. Cancer usually does not come and go. ...Read more

Breast disease: I am sure you are concerned about breast cancer. Breast cancer affects 1/8 women. Have your physician examine you. For your age it could be many things, although cancer can be one of them, its not as common in a 19 y/o patient. However, get a proper examination and if of concerned get a biopsy. ...Read more

Needs work-up: Many conditions can cause the feeling of a lump in the breast, but certainly you should see your doctor and have this examined. You may need a mammogram and further work-up, especially if there is a family history of breast ca, even though you are young. Some "lumpiness" may occur with your period and then resolve. Also, the swelling near your collarbone and l armpit need to be evaluated. ...Read more
