The symptoms of CIDP (Chronic Inflammatory Demyelinating Polyneuropathy) include numbness, tingling, burning and weakness, generally occurring in the feet first and they gradually ascend to involve other parts of the body. One of the first signs that could develope is a foot drop, where patients develope weakness in their ankles and as a result tend to trip over their feet, or they could develope numbness and tingling in the feet and toes which gradually spreads to to the other parts of the body. Other organs could also become involved including inability to adequately empty the bladder, nausea, vomiting, abdominal fullness or bloating, diarrhea, or constipation, low blood with dizziness, or trouble maintaining an erection. The severity and the combination of CIDP symptoms vary. Some could have only numbness, pain, burning, and tingling only, others have weakness only, and some have weakness, numbness, burning, and tingling. In some patients CIDP could be one of the most aggressive types of neuropathy. The patient could develope complete paralysis and have severe burning, numbness, and tingling. In the aggressive types of CIDP the pain can't be controlled with the most potent pain killers. Others patients have a very slow progression with mild disease.
