HTML>Your symptoms are shared by many people who are intolerant of gluten. Joint pain occurs with a moderate frequency.
Variation in time between eating gluten and onset of symptoms is also common.
However there are many other conditions that can produce such symptoms, so do discuss this with your Doctor.
I simply avoid all manufactured foods that may have multiple ingredients and eat rice, potato, maize, meat, fresh veg, fish etc. This can be a very healthy diet and avoids the risk of unknowingly eating gluten from wheat, oats , barley or rye.
If all your symptoms clear after a month on this diet, then you have probably found the cause, but remember that a doctor can do blood tests for some gluten allergy before you change your diet, but not after.
