<s>[INST] Good Morning. My father has back pain, which he fears may be a recurring spondolytis (excuse the spelling) due to lack of exercise in the last two months. The time 12:50 am, and the two pain killers which are available at the house are Crocin Pain Relief and Drotin - M. Please suggest? [/INST] Hi there I would suggest that you give him crocin 1000 mg dissolved in water immediately .Crushing and dissolving it in water will get it instantly absorbed in the body resulting in faster pain relief .Drotin or Drotavarin is an anti spasmodic drug which is mostly used for abdominal spasms and its analgesic effects have yet to be proved .Crocin or paracetamol is a very safe drug and can be given upto 3 to 4 grams daily without any side effects .Complete bed rest and hot fomentation is recommended .I hope my advice has helped Good luck </s>
