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.
It is a non-steroidal anti-inflammatory drug, or NSAID, used to relieve the pain and inflammation associated with rheumatoid arthritis, osteoarthritis, arthritis of the spine, bursitis, tendonitis, gouty arthritis, and other kinds of pain. It is given in capsules, liquid, or suppositories.
