Hi, read your post. Consider trying something that is ancient. Warm Castor Oil packs. Edgar Cayce( his Books are very interesting... he wasn't a quack). Hw used Castor oil treatments for a variety of conditions. Castor oil is " not toxic and draws out pathogens/bacteria that should not be in your body that have potential to cause pain, inflammation and list goes on. There is tons of info for the use of non toxic remedies such as Castor oil.
This is a natural treatment which cause no harm. Look up castor oil treatment on you tube and internet. There is a multitude of conditions castor oil is used for these days and have been used for hundreds of years.. People did not have drs and or run to CVS because they were not available. Sadly doctors are all over the place with a diagnosis. IF they cannot figure it out you will just be referred to another doctor. Has your daughter been checked for Lyme's disease? No deodorant to be used either. There can be alergeries that may be present and not be aware of. All these things mentioned can be addressed. As my grandmother used to say. In years past people did not have drs or cvs. They found ways to cure themselves especially the Native American Indians. Hot warm wet pads under arm with the castor oil may draw out what ever is not draining under her arm pits. A small round water bottle bag.. is useful too.
Castor oil & Manuka honey are also used for neuropathy with. people who have diabetes. Hope some of this helps. I understand how frustrating it is when we don't have a proper diagnosis. Please keep us updated.
