What Causes Itching Sensation On The Chest Post Mastectomy?

default
Posted on Wed, 14 Sep 2016
Question: I had breast cancer and a double mastectomy 5 years ago. Since then I suffer from terrible itching on my chest, sometimes other areas. Have you heard of this problem? Have you treated a problem such as this? This itching is almost unbearable most of the time. Please try to help.

Brief Answer:
Wrong rewiring is the source of the problem

Detailed Answer:
Thanks for asking on HealthcareMagic.

I have gone through your query and understand your concerns. Let me assure you that I can explain what is going on. As you must already understand that while your breast was in place a lot of nerves supplied the area. Signals were constantly passed to and from this region. But once the breasts were excised, these nerves lost their job. With time the flow of signals to and from these nerves came down. In the meantime some of these nerves rewired and therefore now the signals flowed to indicate something different. So, what was previously the switch for the light, with the light now removed, that has become the switch for the fan. So, whenever your body presses the light switch, the fan gets running. That is exactly the thing going on in your case. The sense of touch (could be sense of breeze on skin) or something else has now been rewired to sense of itchiness. This is called 'referred sensation', a slight deviation of the mechanism behind the sense of 'phantom limb' in case of amputees.

The only thing you can do is to ignore it. If you can ignore it adequately, the sense could rewire once again. That is all I can say.

Feel free to write back.

Brief Answer:
If the rules are followed, giving steroids should be fine.

Detailed Answer:
I understand. If it is unbearable, steroids might need to be given. They are safe provided that they are given in proper dose and are eventually tapered off and not withdrawn abruptly.
