New diagnosis

Hi I’ve just been diagnosed with OA Of the knee after severe acute pain and a trip to a&e. I was given pain killers and a fact sheet with exercises etc but the pain is not subsiding and I can’t bend my knee still. I wondered how long it might be before it will settle down so the pain goes and I can walk properly again. I’m trying to rest but have a 6 year old. I’ve ordered glucosamine chondrites today and am using voltarel gel along side the painkillers

any tips or help in what to do next would be helpful. I’ve got a call with my go tmw.

many thanks
