Hi, Thanks for the query. I understand your concern. Erotica90 is an anti inflammatory drug , used for relif from pain & inflammation. You had good relief with it... but have symptoms like mouth ulcers, swelling of upper lip... It seems to be allergic reaction, I would advise to stop the medicine immediately & consult your doctor earliest.. more so if you start breathless/ wheezing. You can take anti allergic pill like avil to start combating allergic reaction .. if you can not meet the doctor urgently. Though you got excellent results...it may not be possible to continue with it. The symptoms need to be evaluated to confirm allergy. He may give you a course of medications to stop the reaction/ advise another drug or combination of drugs for your pain. You can use Duoflam/ pirox gel for some relief. Physiotherapy plays an important role in long run management. Start it after pain relief is attaineded. Thanks.
