Hello,
Metallic taste in your mouth might be due to WD 40 inhalation accidentally, it contains toxic chemicals & cause acute health problems.
You should have got into fresh air immediately as you inhaled WD 40. Never do it deliberately because even small amounts may affect you due to rapid entry through bloodstream into the lungs.
Stay in the fresh air, drink more water, brush the teeth, gargle with warm saline water.
However, you are suggested to visit ER, get clinically examined to detect any serious problem. Neglect will only result in loss of appetite,
weight loss or
depression. Get examined get treated.
Stay away from stress & anxiety, take an analgesic for headache.
Dehydration and stress also cause headache. Take soups, juice & water & stay at rest.
Your treating doctor will detect the cause of
high blood pressure & treat you accordingly.
Hope I have answered your query. Let me know if I can assist you further.
Take care
Regards,
Dr Nupur K, General & Family Physician
