My mother (55 years) is diabetic and has chronic liver disease. She has been suffering from severe right knee pain for almost 2.5 months. She was admitted to cmri hospital with low hemoglobin count as well and upon diagnosis it was found to be septic arthritis. Arthroscopic lavage of the knee was done and 5 units of blood was given. Upon her discharge the pain is almost nil during the day but very bad in midnight. The antibiotic linezolid 600 she was taking has been stopped after 7 days as per doctor's instructions. Please suggest what should we do, if we should consult the doctor again or give the antibiotic for another few weeks as she is unable to sleep properly in night.
