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.
NSAIDs are used to relieve pain related to the following conditions: 1  arthritis, osteoarthritis, rheumatoid arthritis, ankylosing spondylitis, gout, pseudogout, psoriatic arthritis, juvenile arthritis. 2  muscle sprains and strains. 3  minor injuries and trauma pain.  headaches, including tension headaches and 1  migraines. some types of eye pain and ear pain.
