Can you help, for the past few months I have been experiencing pain in my right shoulder from the shoulder blade to the top and down my upper arm and the right side of my neck which never goes away.

I keep getting a recurant sore throat now my chest is now feeling raw at sore. Suddenly the pain in my throat disappears then I get pains which starts in just below my knees and goes up to my hips and the bottom of my back.
Its like a deep niggling, gnawing pain which feels like need to stretch out. It gets to a point I just need to stop, even driving hurts, I don’t get relief from sitting, lying down.

I get maybe 1 weeks relief from the leg pain, then it’s back again. The sore throat then the leg pain goes round in a cycle and has been since July/August.

I have had blood done by the doctor in October who told me liver and kidney function were all normal, blood count and thyroid normal but my ferrous levels were low so I was given ferrous furmate tablets to take for a month.
I was also prescribed Omeprazole for heartburn and acid.

I have been prescribed pain killers, which don’t touch the sides and venlafaxine twice a day (not sure why!).
