My daughter (She is 9 years) encountered Dengue her platelets came down till 90K but she recovered well, But now after a long time she is complaining with Knee Joint pain, I do not see any significant swelling in her knees but she complains kee pain often. Is this because of Dengue or it can be some thing else, What are the tests you recommend to be performed and what specialist I should contact in person. Amit
