First, go to the the doctor to find out what he would prescribe. Then get 2 or 3 second opinions.
Buy the medication that they prescribe. Use it faithfully until the first batch is gone. Or if it is several different medications to be used one following the other, continue until the first "batch" is completed. When it is gone, get onto nutritional therapy from a health practitioner. Don't continue with the medication.
Why do this? The medication will kick your body into all kinds of actions to fight your problem. It will do this because virtually all medication is poison, and makes your body work very hard to get it out of your system. The hard work your body does will often take care of the problem you had in the first place.
What will the nutritional therapy do? It will wash the remaining medication poison out of your body, and strengthen your immune system (which was weakened by the medication), and give your body the material it needs to rebuild itself from the destructive forces that the medication did.
Depending on how old you are, and how healthy you are, if necessary, repeat this cycle 6 months to a year or more later. Ask your health practitioner for guidance.
