<s>[INST] We ll I ve suffered from arthritis since I was a young teen.. My knees would chronically swell I would get them drained they would swell... And so on... I had two orthoscopic surgeries in my left knee only to be told that I have inflammation of the synovial membrane... :( for years it stopped for no obvious reason now my right knee is swelling ... But the funny thing is only do these episodes happen in the spring.. I can down hill ski in winter without worries? I ve had my blood checked for rheumatoid arthritis and it came up negative... What is going on with my knees? Cause I feel like a weather barometer ...:( [/INST] Brief answer: SynovitisDetailed Answer:Hi,Noted your concern.Synovial membrane produces excess fluid which collects in a sac and cause the swelling in joint and pain.According to Ayurveda, this condition can be termed as sandigat vata.Ayurveda has many herbs that can help in reducing swelling and pain:-:-Triphala,,guggulu preparations,praval pisti ,coral (mukta pisti),ashwagandha,shatawari etc.:-Ayurvedic  panchkarma procedure  janudhara (janu means knee),shirodhara can help to reduce  your problem .:- practice of yoga and meditation .meditation provides a way to achieve the balance.:-Healthy diet, habits and life style can help to maintain joint health.I would suggest you to visit a good Ayurveda practitioner and discuss your problem .I hope my reply has helped you.
