Question : Recently had TDAP, knot has formed at injection site.
Pain in armpit of arm where TDAP was done. There is some swelling and lymph nodes feel like "pebbles". Went to urgent care and they "suspect" a reaction to vaccine. They did no testing Pain and swelling now getting worse and now getting pain on back of arm by elbow.
Any ideas?

Detailed answer...
Hello,
Thanks for the query.
I have read your query and understand your concern.
Your symptoms seem to be due to reaction to vaccine and pain is due to inflammation of local lymph nodes.There is nothing to worry as it should subside gradually.
You may take ibuprofen 400 mg three times a day for 3-5 days along with local icing and you should be all right in next few days.
I hope it helps,however you are most welcome to revert to me for any further query.
Best of luck
Thanks
