If you have fibro and you’re like me, bras can sometimes feel more torturous than supportive. I have large trigger points all around my upper back/shoulders/neck. Sometimes I just can’t stand my bra straps digging into the muscles. I found a couple of great solutions!
One is silicone bra strap cushions that go under the straps and distribute the pressure, like these ones: http://www.amazon.com/Flirtzy-Silicone-Cushion-Shoulder-Discomfort/dp/B002BZXMCU/ref=pd_sim_hpc_1

The second is reusable adhesive silicone cushions that cover the nipples (preventing embarrassing nipple-itis) on days when I just can’t stand to wear a bra at all, like these: http://www.amazon.com/Nippies-Skin-Reusable-Silicone-NON-ADHESIVE/dp/B001O482W4/ref=sr_1_1?s=apparel&ie=UTF8&qid=1372098771&sr=1-1&keywords=silicone+nipplies+cover

I buy the brand at my local drugstore, so these links are just to illustrate. Enjoy the freedom!
