Here let me tell you the common symptoms of ms. It varies depending on the location where it is affecting nerves and spinal cord. And they are as below:Numbness or weakness in one or more limbs that typically occurs on one side of your body at a time, or the legs and trunk Partial or complete loss of vision, usually in one eye at a time, often with pain during eye movement Double vision or blurring of vision Tingling or pain in parts of your body Electric-shock sensations that occur with certain neck movements, especially bending the neck forward Tremor, lack of coordination or unsteady gait Slurred speech Fatigue Dizziness Problems with bowel and bladder function, Now here you have told redness on skin. As per my opinion this is not related with ms. But change in body temperature and chills can be related if sensory nerves are affected. Here I see there is another possibility of having allergy or skin infection, because both will have again the same symptoms. So I suggest you to talk to your doctor and check with dermatologist also once, let him see your problem physically and then follow the treatment as per his suggest. Take care.
