Hi, I was bitten on my left forearm by a horsefly two days ago; I felt and saw the insect and nocked it off my arm at the time. There s no local redness to the bite area but after a few hours the whole forearm and hand have swolen up markedly, with tight feeling, slightly pinkish skin, tender but no real pain. The swelling has not gone down today and swelling has stopped at the whole forearm/hand, upper arm is unaffected. Is this something I should bother my doctor about? Or will it subside after a couple of days? I ve not had this problem before. Thanks for any advice.
