Hi Guys

3 months ago I went to my GP with a numb and tingly left arm and pain in my neck/jaw. He moved my head and neck around and said I had a trapped nerve in my arm. He said the pain from this could radiate to my collar bone area.

I then kept getting palpitations so went to the GP who did an ECG which was declared normal.

Now for the past few weeks I keep getting a pain/feeling which is similar to indigestion in my upper left back. It doesnt stay long and just stabs me but then goes again. I have noticed it is worse when sitting in bath or when on laptop now. This has gone on for weeks so I assume any heart related back pain would maybe be more severe?

I have no chest pain

Thanks
