Can fever and joint pain occur due to TB?

Hi doctor,

My daughter, who is 7 years old, is on ATT for the last five months. She had fever and knee joint pain on the right side for over one and a half month. Mantoux was positive and CT and X-ray showed hilar lymphadenopathy. Bronchoscopy, GL, bone marrow and CSF were done, but no AFB found. Malignancy also ruled out. Based on Mantoux and CT, ATT was started. Still fever persists though it was better for a few days after starting ATT. The fever used to be low grade and rising high at times and we had to give her Paracetamol. When she has a fever, she also has pain on joints such as knee joints, shoulder joints and sometimes, on sole. Once, she had a high fever of more than 101 degree Fahrenheit and she complained of acute pain in left knee and right shoulder joint. The fever did not go fully even after giving PCM 250. By the evening, the fever has gone completely and so was the pain. She was very active the next day. Again, she had some fever after two days. In the last 8 days, we did not give her PCM, but of course there have been low grade fever every third day like which goes again and she is still having problem with stairs (walking down).

Also, we have noticed that her palms are hot most of the time. While holding her palm it feels so hot as if she is having high fever, but her forehead is relatively cool. She has hot palms even when she is not having a fever. I just wanted to know how long the fever will persist after starting ATT? What is the reason for joint pains? Sometimes, during fever, she develops nodes and red rashes in her sole, which is very painful. I have attached the photographs for your reference. Also, I have enclosed the test results of various investigations. Please give your opinions. I am really worried.
