My joints have always been relatively well controlled, with the main one giving problems over time being my ankle. At the moment I'm in between meds, waiting for approval for rituximab so 'only' on 10mgs a day of pred along with anti-inflammatory and hydroxychloroquine. It is the first time in my 2 years since diagnosis that I haven't been on a DMARD stronger than hydroxy, so not sure if it's that, but had my flu jab yesterday and felt my ankle get progressively worse during the day, and today can hardly walk! I was wondering if it may be caused by my immune system having to kick in due to the flu jab, and thus also 'kicking in' and attacking my joints! Just wondering if anyone else has had their joints flare after the jab?
