Years ago, sodium hypochlorite was used to chlorinate pools. It is basic, pH greater than 7. And I think ordinary hydrochloric acid was used to drop the pH back to 7. I don't know if these are still used. Sodium Hypochlorite ([math]NaClO[/math]) was used to chlorinate pools. If you want to lower the pH, try adding HCl.
Because most episodes of back pain have inflammation as a contributing factor, anti-inflammatory medication such as non-steroidal anti-inflammatory drugs (NSAIDs) is often an effective pain medication treatment option.
This enzymes are produced by the cells of the body, and are responsable for the creation of the agents called prostaglandines, which promote inflammation, pain and fever. The most known NSAIDs are : Aspirin, Ibuprofen, Naproxen, but the NSAIDs list contains many brand name drugs. If you want to use these drugs it is very important to discuss about this with your doctor. If your purpose is to suppress inflammation, then you need to take NSAIDs at higher doses and on regular interval.
