Hello,

Thanks for posting your query.

It will be very helpful for me in understanding your condition better if you could answer some of these questions:
1) When was your last menstrual period?

2) Did you start the depo shots recently?

3) Are you taking any other medications?

4) Is the the first time you are having irregular bleeding and backache?

Backache, irregular bleeding, spotting and GI disturbances like nausea, bloating and diarrhea are frequent side effects of Depo Provera shots. However metallic taste is not a frequent side effect of the drop shots and can be due to gastritis or GI infection.

In fact lower back ache, metallic taste and diarrhea can be due to GERD (gastrointestinal reflux disease) or gastric infection.

Metallic taste is caused by caused by anaerobic bacteria that live within our bodies. These bacteria can grow in number very quickly when given the right environment or food source thus causing a bad taste in mouth. It can be due to dental caries, gastro-esophageal reflux disease, medications like antibiotics, vitamins and antidepressants, poor oral hygiene etc.

I suggest you to get an examination done from a physician and get GERD ruled out.

Till that time, you can fight against the metallic taste by having citrus juices, lemonade and foods marinated in vinegar. They not only break through the taste, but also help in saliva production that helps in washing away the metallic taste. Every time you brush your teeth, make sure to brush your tongue also. It will help in lessening the metallic taste. You can use some oral mouthwashes also. This should help.

Hope this answers your query. If you have additional questions or follow up queries then please do not hesitate in writing to us. I will be happy to answer your queries.

Wishing you good health.
