What may have started as an epidermal cyst, obviously became infected....if you have that history of fever, etc.

Once the infection starts, it is a new ball game!

If you have drainage of pus, and blood still after all these months, something is wrong.

Hair will fall out after a trauma, or infection like you had. I lost over 1/3 of my hair after a major surgery from a C-section with exploratory.

Infection puts a huge strain on you... to heal you need good quality protein, and zinc in your diet.

The drugs they gave you? You need to know what those were.
Some of the drugs used can cause neuropathies. Flagyl, Levaquin, Zyvox...are some.

I think you should focus on that infection. Make sure it is GONE.
You need a current renal panel to make sure your kidneys are working correctly, now.

Gabapentin can cause low platelets and also hyponatremia, in some people. Low platelets= bruising.

If you did not have your PN symptoms BEFORE this surgical fiasco, then I would look to that, right now, and get it fixed once and for all. Sit down with pen and paper and write down what you had before the infection. And then the things that came after in another column. Take that to the new doctor, preferably an infectious disease doctor, to see what he/she can find out.

There is a form of breast cancer called inflammatory breast cancer which is confusing to diagnose.

It is more common in younger women and may resemble an infection. I hope you don't have this.
