Itching in throat and coughing . Garling regularly to get rid of cough but still no relief. No cold neither fever. Experiencing weakness. I'm going through Multiple Sclerosis hence weak right limbs which increases when suffering from cold. The coughing is problematic in evening when temperature in environment drops. Increase in body heat. Experiencing fatigue as well. Recently took intravenous Rituximab medication. Sleep is good, no problem there. Having protein supplement regularly due to deficiency. No problem in bowel movement. Consuming homeopathy medicine for MS everyday and also B complex supplement like Optineuron and neurobia. Also, 2 weeks ago had lot of coconut water and banana but didn't experience cold back then and travelled from Mangalore to Thane at that time. I don't consume milk products like curd etc which would facilitate cough formation. Does this subside on its own? Or chances of some infection? No one infected around me hence eliminated that probabilities. Thank
