<s>[INST] I had operations many times for my gastric ulcer and had 15 bottles of blood within the last three months. Now my skin especially around my operative scar at my abdomen got severe itchiness and paresthetic which wake me up during the night. Do I need medication like Calcivita plus any local application ? [/INST] HIWell come to HCMI really appreciate your concern, this could be hypersensitivity reaction, if I would be treating physician of this case then I would treat this case with the following medicine 1) Tab Hydroxyzine 10 mg three times in daycondition would be fine soon, this is nothing to worry, have a nice day. </s>
