Hari Om !
It's better to consult an expert Ayurvedacharya. Firstly avoid milk,
buttermilk, coffee, tea, alcohol, smoking & processed foods and exercise
the affected joint every day religiously. If possible, a few Ashanas
(Yogasana) will help you to get rid of the problem but you should start
Asanas in the presence of an expert only. Take lemon juice in a glass of
hot water (as hot as you can drink) and drink it, 8 to 10 times a day.
Initially for a few days you might feel that the pain is increasing but
gradually it decreases. If you believe that sour things are bad for
joint pains, it isn't true all the times. If you are afraid anyhow,
regularly take 3-4 walnuts (akhrot) on an empty stomach in the morning.
This will give you the result........... I am sure.
With best wishes,

Swami Brahmavidyananda
