<s>[INST] Hi my name is Hayley, my brother in law has been taken into hospital because he is not able to lift his arms up, he has just been to the caribbean, the doctors at the hospital are unsure what the problem is and running tests, they are presuming it may be glandular fever at this time is there anything you may suggest? Thank you Hayley [/INST] Hi, Consult an orthopedician and get evaluated. We have to rule out possible ligament or tendon injury. Hope I have answered your query. Let me know if I can assist you further. Regards, Dr. Shinas Hussain, General & Family Physician </s>
