They did some tests swab on throat, nose and blood work and results came negative. I took the medications but my cough got worse keep coughing every 5 seconds... Then my arm are hurting and when I stand up my leg (back of the knee) hurting and shake. I couldn t stand longer than 5 seconds. I have never felt this before and this is my first time to take the Tmiflu.... I am so worried very worried of how I am feeling. Please help
