my age is 60 years, i am diabetic, taking medicine everyday and keeps under control. if i take some pain relief medicine - like panadol, crocin then within 15 min to 1 hour i get redness and rashes on whole body with heavy itching and followed by stiffness in hands and legs, head gets heavy, with vomiting and toilet sensation. to cure this i am taking Teczine 5 mg. it takes around 20 min to get my redness and burning, itching in control, but leads to Low Blood Pressure (even 70/50). what needs to be done?
