Pain under armpit and breast area.

I am 31 And about 3 weeks ago I got a pain in my left arm pit going into my breast. I feel no lumps, and no tenderness to the touch, I've looked up just about everything and I'm doing exams to much, if I think I feel pain and I come back it's gone..I'm not blessed in this area so I can feel a good bit ...I only have pain, but my mind won't stop thinking the worst. I Have also thought could my breast be growing??? Cause some times it feels that way to...I am a mother of 4 young children and I have no health insurance. I thought it was due to a bra I was wearing so I changed what I was wearing. It feels like I've been bruised and dull pain. It's not constant I've gone a few days without it, but I can't get it out of my mind...I've read something about someone's back well I've been having some serious neck pain to where I couldn't lift my head but I don't know where to go...who to talk to all I want to do is cry because I'm scared...help me please

I can only tell my story, and hope it helps!
When an ache started on the left side of my chest about four months ago, I disregarded it, associating it to anxiety. A few days later, the pain went from an inconvenience, to debilitating within an hour, expanding to my underarm and down my hand. I was at work, desperate for every hour, so I didn't want to leave. A friend of mine noticed I was pale, asked what was wrong, and immediately went for chewable aspirin, convinced I was having a heart attack.
Work sent me to the closest er, where the radiologist told me I had a small aneurysm on my aortic valve. I quit work, went on blood pressure and antianxiety meds to keep my stress to a minimum, wrote up a new will, had a dozen restrictions on activity and diet from my doctor, and tried to function as all of my medical treatment was based on one radiologist's report.
The pain never hit so bad again, though I perpetually had pressure in my chest, and discomfort under my arm.
Until a few nights ago.
I was watching a movie with my son, relaxing on the couch, when I felt like I was hit with a sledgehammer in my left breast. My arm, the side of my chest, and underarm felt as if it had been tourniqueted too long and were about to explode.
I went to the er of a wonderful hospital, where they told me after another CT... That there was nothing in my breast- nor was there ANYTHING wrong with my heart. The nurse pressed on my back, right behind where my heart is, and I jumped- because of all the pain, I hadn't even realized it was super-sensitized.
Come to find out, the discs in my upper back are herniated, which has caused all of my symptoms, even though it was all on one side. C7-T2 disc damage is becoming more and more common as more people than ever are slumped over computers, though mine was from repetitive work with my arms.
My first advice would always be to check your heart- these are symptoms of a heart attack for women(even nausea). Obviously, always look into the danger of breast cancer. If you don't find anything there, though- take a look at your back!!! I'm stuck with this agony which no pill or shot has been able to touch for at least a few months, but if I wouldn't have been so terrified by my first diagnosis, and asked for more tests, the further damage to my discs would have been preventable.
Good luck, everyone!

To say that cancerous lumps are not painful is a myth. I was diagnosed with Stage 3 breast cancer at 44 yrs old two yrs ago. My tumor was very painful! Please do not dismiss a possible malignacy just because you have pain. Get it checked out ASAP!

Hello, I have had an off and on aches around my left Breast, under the armpit, upper arm and back. Had many checks, have been diagnosed with health anxiety and am awaiting CBT. Can anxiety be that powerful?

Many thanks

I received a callback on March 10th after my annual mammogram March 4th. They said they wanted me to call for an appointment to get an ultrasound on my right breast. I asked the girl that called if I should be worried. She said it could be my breast are dense. I don't know why I asked her, she is not a Doctor. I think if was just someone to talk to in a moment of horror. I called for Ultrasound appointment and the first available is not until March 23rd. I have tried to remain calm about this, but I have also had periods of crying and really just wanting to know if this is something to be concerned about. I also have had slight aching sensation in my right arm and right armpit for sometime. I honestly thought it was probably arthritis because of my age (65).

I too am 36 and my symptoms are exactly yours. Have a mammogram today.

I have now been diagnosed with Irritable Bowel Syndrome and Fibromyalgia because of the armpit thing. I went through heart test gallore etc and scopes just not yet seen the gynecologist to check for cysts as I also get cramps at times. I sought the advice of a natural path who put me on triphala in high dosage for week then one at night and one in morning and until recently it was my miracle drug for stomach although off right now I may have to take again as stomach and nauseau back. I still have the armpit pain and it freaks me out too as I really don't feel like its from fibro but it could be anything dealing with auto immune issues which do run through my family. They just don't know enough about these diseases and they diagnose you by ruling everything else out. Have patience and persistence to let them know your not crazy. You really are feeling weird things in your body, likely food allergy, auto immune or something like that. Btw i am 43 this year so its about that getting older time I guess. :( natural herbs really do help though alot :) :) try a natural path store or magnesium too for nauseu but always consult on what your doing with doc and be careful as they are meds too just ones with very little side effects unlike prescriptions that btw did not do a damn thing for me. I do have pain killers for the dull ache and pain but try hard to avoid them.
