Hi Sunshine. Welcome to HCM. I have gone through your query. Here is what i could make out from the information provided by you. The crawling or tingling sensation on the face you have been experiencing is due to peripheral neuropathy. The swelling of limbs and back you have been experiencing could also be due to peripheral neuropathy. Fibromyalgia is a diagnosis of exclusion( it should be considered only when any other reason could be found out). Your rheumatologist might also be right as some of your symptoms favour the diagosis of fibromyalgia( but it doesnt explain the tingling sensation of face). But it would rather go in favor of Peripheral neuropathy instead of fibromyalgia. Unfortunately either Ct or X ray or MRI cannot confirm the diagnosis of peripheral neuropathy. You need to get an EMG done to confirm the diagnosis. Adriamycin does damage the heart ( causes dilated cardiomyopathy and also causes peripheral neuropathy). The cause of peripheral neuropathy could be diabetes deficinecy of vitamin b12 and some times deficiency of Vitamin D3. Please get your blood Vitamin B12 and Vitamin D3 and sugar levels checked and get treated accordingly Even if everything comes as normal ,Taking injections that contain Vitamin B12 and pyrridoxine and thiamine like Neurobion forte or methycobal should definitely help you. Hope you got the answer you were looking for. Wish you a speedy recovery Take care Dr SAI RAJESH
