Hi all , I had a doubt regarding shared needle . I went for medical test due to job purpose ,my company asked me to get leprosy test , syphilis and HIV for foreign visiting . So , I went for clinic for that test . There I had bad incident , the one patient who came earlier to me was foreigner whose age is 55 visited for AFT and lab tech person took his blood sample and then few seconds later I went inside room , he took my blood sample without showing whether it was new needle nor not (Venipuncture method) and next day later I got my reports  , all are negative [leprosy,HIV,LFT] and after this incident 2 days later i got erythema papules on chest , arms  and 10 days later sore throat followed by burning sensation through out the arms and body and muscle aches , joint pain and next 15 days developed vasculitis , headache , peripheral neuropathy symptoms on feet and palms ,Teeth pain , enlarge lymph node near pre auricular due to teeth ( lasted for 4 days ) . Could it be shared needle?
