Iam a 35 year old female.Three months ago I was hospitalised with Pneumonia. During my hspital stay I twisted my right knee slightly whilst bending down. Once I left the hospital the knee got worse everyday and was very inflammable. A week later the left knee started but has never been as bad as the right knee. X-rays and a magnetic scan showed to bone or cartilage damage. they have sine done extensive blood and urine tests as well as tests on the fluid of both knees. Everything has came out negative. By a process of elimination the doctor decided it was Rheumatoid Arthritis brought on by a familt gene because my brother suffers from Psoriasis. He then injected both knees three months later with an injection of cortizone derivative after Indometicina anti-inflammatory tablets proved useless. I have been told to do no exercise and rest however this is impossible as a single working mother. There has been an improvement since the injections yesterday however will this reoccur Any thoughts or advise?
