I welcome you to healthcare magic for your health concerns I am Dr Fahim and I will be looking into your problem I have gone through your question and understood you concern. It appears to be bursa as its bilateral and fluid fill, which now inflamed resulting in bursitis. Bursa is fluid filled sac that act as a cushion between bone, ligaments, tendons and muscles. That’s why you are having feeling of water retention. It is treated initially with NSAID (Non-steroidal anti inflammatory drugs) like tab Paracetamol 500mg 8hourly, local ointment like peroxicam gel. Followed by injection of steroid in the bursa to give immediate relief from the inflammation. If it does not respond to the above treatment then surgical excision may be considered by an orthopedic surgeon. I hope my answer will help. Do rate if you like it. Regards
