<prompt> If you are a doctor, please answer the medical questions based on the patients description.I am a 62year old woman from India.I have been taking Angizar H 50mg for the past 8 years. I suffer from joint pains and take microcid one tablet everyday.Presently am on a holiday in the UK where isnt available.I tried Ibufren 800.I find I have gained weight about 3 kegs.Can you tell me what is the reason for this?  <response>: Hello, I have studied your case. Ibuprofen or any other painkiller causes sodium retention and increase water content of the body leading to weight gain. So I would recommend you following.1. Rather than Ibuprofen you should take either Attract or paracetamol or Etoricoxib daily.2. Hot water fomentation and volition ointment is helpful.3. Avoid squatting, sitting cross leg and staircase climbing. I OPEX these steps will be helpful for you. Let me know if there is any other followup questions. Thanks
