I missed a shot 3 days ago. Its definitely like none other I've missed. Its swollen very large,it's real red. Its hot,has got me with limited hand use. Also feels as if it's got my bicep cramping and the spot is on my forearm above wrist.
Put dotted lines around it using a felt pen and keep an eye on it watch for any growth if you don't want to go to the hospital right now then this is your best bet. I really suggest going to see a doctor though it sounds like its already infected man. Don't play around with this stuff you could lose a limb.
