To explain my medical history would take pages but in a nutshell, I had cancer 10 years ago. I have just been diagnosed with severe aenemia. They don't think it's cancer (nor do I) but they need to rule it out so lots of hospital appointments and investigations coming up. In the meantime, my consultant referred me for an Iv Iron infusion. I had it on Wednesday. That evening, I was exhausted but I worked yesterday and felt I had slightly more energy. Then, I woke up this morning with the most strange pains. It was like a gripping pain in my abdomen/chest which released a bit then moved to my back before moving to my arms and shoulders. Pretty painful. This was happening intermittently. I took the day off work as I felt so rough. I've slept this afternoon, taken painkillers and rested and it's eased a bit. I am still experiencing some pain. I called the hospital and they said this can happen and I should be okay in a day or 2. Google said the same! Has anyone else experienced similar issues after iron iv and if so, how long did it last?
