Suggest Treatment For Swollen Red Lump At Injection Site After Injecting Methamphetamine

Question : i have not long ago had an injection of meth and i missed a small amount, the area at the injection site has a swollen red lump and a blister in the middle, my arm is aching and it feels really cold (although i have had ice on it) I am taking amoxycillin antibiotics and brufen/codeine over the counter pain releif tablets for other conditions. Do i need to be concerned? how can i stop the aching etc...

please explain what is injection neuropathy?

So do i need to see a doctor or not? What can i do at home to ease the symptoms?

so its been a few hours now, the pain is minimal, the swelling has remained unchanged but not worsened and the blister has disappeared without a trace. Gee im glad i didnt spend the night waiting in emergency at the hospital, and relieved I didnt have to put myself at the mercy of ignorant people with harsh assumptions of a life they do not understand, nor try to. PS I have not said at Any time that i am taking tylenol for pain relief, and am s urprised frankly that you would even suggest it given that i clearly stated that i am very sensitive to pain medications and suffer allergic reactions to many, as upon googleing the drug i find its not recommended to those sensitive to medications or tending to allergies, furthermore that in the case of an allergic reaction the symtom would be a skin inflamation, rash, blistering etc! and just to add it also can be fatal when taken with more than 3 glasses of alcohol in one day- didnt i mention i am also an aloholic, consuming an average of 8 adult serves of alcohol daily. In assumption had i taken your advice i would be dead or close to it, so id just like to say thankyou very much your help, it was so worth the $15 i paid. Goodnite
