Hi doctor, I'm 41 years old, I recently had an operation to have 3 fibroids removed now I'm back at work now at least 3 months, and the last few weeks I have had a stabbing pain in the back of my chest , I have had a chest x-Ray done and my results have come back all clear. Since the pain in chest started I noticed I would have numbness in my arms or pins and needles in my hands this keeps happening, and my left knee if I sit for long periods I have severe stiffness in my knee when I try to get up and stand and I feel my body aches with pain too, should I be worried? All my bloods have come back clear as I made my gp check this a second time. Sonya is my name
