Hello! Thanks for putting your query in HCM. I am a Gastroenterologist (DM). Yes this level can be reverted back It may be because of chronic NSAID intake Instead of NSAID take tablet tramadol plus paracetamol as it is a good analgesic with minimal side effects. It is not nephrotoxic and do not lead to fluid retention also I hope I have answered your query and this will help you. If you have any further query I will be happy to answer that too. Remain in touch and get-well soon.
