<s>[INST] I have had a cough around 3 weeks now, which just feels like a tickle that doesn t go but due to the amount of coughing my ribs have a bit if pain in them. I discovered today I woke up with red blotches or patches on my tongue and am quite worried. I feel nauseous sometimes and very tired, what could this be?? Very paranoid!! [/INST] Hi welcome to ChatDoctorthis may be allergic AO viral infection the cough is due to that if you do not have fever I would advise you take SY Granicus DC 2 to 3 times a day you can add Cronin 650 if it hurts while coughing also taking hot water to sip and cough lozenges would help the b;notches and patches weakness are due to vitamin deficiency you can take becadexamine along with vitamin C tab daily hope this helps thank you </s>
