Hi and welcome to Healthcaremagic. Thank you for your query. I am Dr. Rommstein, I understand your concerns and I will try to help you as much as I can.
These are typical signs of
lymphangitis which is bacterial infection of lymph chanels in arm and this is not uncommon after bites or injuries.
Hi and welcome to Healthcaremagic forum. I understand your concerns.
If there is just clear
redness then you should not be concerned but if there is pus discharge,
fever, then it may indicate more severe inflammation and you may need antibiotics. Also if pain is progressive you should do lab findings to rule out blood
poisoning.
Till this, you should rest, apply cold compresses, keep arm elevated and take nonsteroid painkillers such as ibuprofenum or
Diclofenac.
It is however expected that symptoms may persist even for up to5 days but just watch for these signs that I have mentioned and if these occur, go to ER to have intravenous antibiotics.
I hope I have answered you query. If you have any further questions you can contact us in every time.
Kindly regards. Wish you a good health.
