I'm sorry you're uncomfortable. Obviously, without an examination and a few more details about your recent surgery and medical history, it won't be possible to identify the cause of your symptoms. However, there are several thoughts that come to mind here:
Your breasts are supported by ligaments -- Cooper's ligaments
-- that get stressed when the breast is jostled. If your lumpectomy
was near a Cooper's ligament, exercising may have stirred up some residual inflammation that is now irritating the ligament and triggering your pain.
If you've been relatively sedentary since your surgery, you may have developed a blood clot in one of your legs. Walking may have broken a fragment from the clot, which could have entered your circulation, travelled back to your heart, and thence to your lung. This condition, called pulmonary embolism
, is XXXXXXX
I presume your lumpectomy was performed to evaluate a breast mass that may have been cancerous. If the lump was malignant, there's a small chance your pain is due to cancer involving your chest wall.
Your pain began shortly after eating some vegetables and drinking cold water. An esophageal spasm could trigger the type of discomfort you described, and the pain might even persist for several hours after the initial spasm calms down, particularly if you have a bit of acid reflux
in the bargain.
Finally, I see from your historical data that you're at an age where heart disease
becomes an issue. Thus, it's possible your chest pain
is due to ongoing angina
(heart pain). Usually (but not always) angina gets worse with exertion and resolves or gets better with rest. In contrast, if certain movements -- stretching, reaching, or twisting -- aggravate your pain, or if pressing on your chest increases your pain, it's more likely due to something in your chest wall than it is your heart.
The bottom line here is this: since it isn't clear what's causing your pain, and since it's possible there's something serious going on, it would be prudent to see your doctor as soon as possible.
I'll be available to answer any additional questions you may have.
I hope that helps, and I hope you feel better soon.
