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 usually indicated for the treatment of acute or chronic conditions where pain and inflammation are present. Nonsteroidal anti-inflammatory drugs are powerful analgesics, especially for nociceptive pain. NSAIDs also are effective in some neuropathic pain syndromes when used with other analgesics.
