I have a friend experiencing some pretty sever body aches, having some trouble breathing without having to cough, and she has a irregular taste of rust in her mouth. She has enlarged lymph nodes and has already been to the dr. before but has not been back since the new symptoms. Is it possible these new symptoms could have anyting to do with her enlarged lymph nodes? Possibly lymphoma?
I would recommend another visit to the doctor. Sometimes developing new symptoms helps the docs diagnose.
Here is some info I found on metallic tastes in the mouth from atlanta dentist:
Blood cells contain hemoglobin which carries oxygen. When blood breaks down, iron is released and causes a metallic taste in mouth. Bleeding can be from the gums, sinuses or nose. The taste can get especially bad when someone has post nasal drip and the dried blood sticks to the back of the throat. If bleeding gums are the cause there is often bad breath associated with the bad taste.
Another uncommon reason for a metallic taste in mouth is due to small electric currents in the mouth. When two types of metals are used in two different dental fillings a battery can be created. Some believe that it's due to the mercury leakage from dental silver/mercury fillings.
Many oral or IV medications such as thyroid medicine, penicillin, and lithium can give a metallic taste in mouth. When someone is allergic to a specific food, the food can often be detected even in extremely small amounts. Food allergies, such as with sulfur dioxide, can also cause this. Some gastrointestinal disorders can be aggravated by food allergies and cause burping, dry mouth, thirst, rectal itching and a metal taste. High protein diets can cause benign dietary ketosis. This has also been associated with a metal taste.
Chemotherapy, radiation therapy, or cancer itself can cause a metallic taste in mouth. It has also been associated with B 12 deficiency, zinc deficiency, Bell's palsy, Strep throat and Sjogren's disease along with anything that causes dry mouth.
