How Do I Ease the Pressure in my Chest After a Breast Reduction?

I do not want to sound like an alarmist but I am concerned about your description of the chest pain and hip pain. The description of “massive pressure in my chest” and “hips feel like you're being crushed” are not typically  heard after the breast reduction procedure.

I would suggest contacting your plastic surgeon ASAP.  If he/she is unavailable I would suggest an emergency room visit.  It's important not to miss  a diagnosis  of deep venous thrombosis and/or pulmonary embolism ( which can be fatal).

Sorry again if my response causes anxiety but it is much better to be safe rather than sorry.

I hope this helps.

From your posted description you need immediate care! Seek emergent care from you surgeon or go to closest ER. Please this could be serious from your written description. 

Most plastic surgery offices provide extensive discussions and /or lists of expected occurrences after all surgical procedures.  In the immediate post-op period, a deviation from the "expected" course of events warrants a call to your surgeon.  Extreme symptoms mandate a trip to the closest ER.  Don't ever hesitate to call your doctor for clarification and reassurance.  Sometimes, it is only a tight dressing causing the "emergency".
