I am looking for any insight someone may have to help me out.
I have been suffering from constant pain on my left side for about 2 months now. It seems to be a deep muscle ache, and NOTHING helps it or makes it go away. Some days it is worse than others, but it is alwasys there. I have had neck/back x-rays and they were normal. I've seen a neurologist and he says my exam is normal other than I don't have any reflex in my left knee. I saw a reumatologist, who ran a ton of blood work which was all normal. I've had an MRI of my brain and it was normal. I am really at a loss here and desperate to find something. I am currently being referred to a Neuromuscular specialist, but I don't know when I'll get an appointment.
Symptoms:
Aching in left side of face, neck, shoulder all the way through finger tips. Anching in lower left abdomen down to hip all the way to toes. I have not noticed an weakness or tingling, just a constant ache.
I also experience muscle spams inside my chest on the left side which are very painful, it does not feel like my heart but is none the less worrisome.
Any insight someone could provide would be greatly appreciated!!
