Hi, my 23 yr old daughter crouched down at work and felt something go. Knees have been swollen for a 3 weeks now. No pain, no redness, no puncture marks but its not going away. Shes hobbling about and the knees are stiff. We took her to a&e when it started they gave her naproxin and the gp signed her off work last week saying she had joint pain(she def. Hasnt). Shes done RICE as treatment but nothing is changing. Has anyone had this'water on the knee', and what happened ? I'm very much wait and see but she had a slew of other conditions in the past few years (septic athritis) and I dont think the gp surgery in lockdown works well . Any advice gratefully received.
