Allergic Reaction to Amoxicillin and Joint Pain in Toddler

My middle boy has had serious joint pain like this and sometimes you cannot even touch certain parts of his body because they are so sensitive. About a year ago, his ankle hurt so bad he could not walk, literally. I took him to the doc who found that indeed it was growing pains. Turns out that my son who is VERY tall for his age is going to run into this with his joints during childhood. Evidently very tall children sometimes even break small bones in their joints (especially ankles) due to fast growth. Bizarre huh?

Needless to say, he did not break any bones but was unable to walk for 3+ days due to the pain. It finally went away and all was good.

I have no idea if this is what has happened with your son, but it is a thought. I also know that allergies to meds can be very odd. I am allergic to many common scripts and one of them I did have some severe joint pain caused from dehydration (I get hives and throw up).

I would just check with the doc or next time call the doc on call to check.

Good luck

Do not feel confident that what he is experiencing is only an allergic reaction. We had the EXACT same situation happen to my son, until we had a formal diagnosis. Does your son have any stomache pain as well? Please check out HSP - it's very rare, but Henoch-Schonlein Purpura - see this link: http://www.medicinenet.com/henoch-schonlein_purpura/artic...
We finally had a GI (gastro intestinal) specialist see him at Children's Hospital in Aurora and she figured it out based on the entire timeline of his symptoms. He is on steroids (pregnisone) currently and is doing great. Best of luck to you - this is a rare disorder that is triggered usually by a severe allergic reaction, or strep. My son also had severe hives, swelling and pain in his ankles, knees and pain in hands. Best of luck to you - and hope your son is out of pain soon, it's awful to see as a parent, I know.

My daughter had this ast summer-She had a severe allergic reaction to the amoxicillin which we were aware of and then her feet turned purple and hands and swelled and she could not even walk-she said it hurt-So long story short after all the blood tests along with the severe reaction she also had a viral infection-after the benadryl and motrin she was back to normal in less than a week-IT IS SCARY, BUT HE WILL BE OK? WHAT did the Ped say? Hope I helped. L.:)

My son had the same thing happen to him on Thanksgiving week, the worst of it being on Thanksgiving day. Every joint on his body swelled up like a balloon. It was a serious allergic reaction to Amoxicillin, just like your son. I called my pediatrician and he just called in a perscription for Prednisone, a steroid. It worked wonders and by the next day he was almost back to his rambunctious self. He didn't get totally better until Sunday. We tried Benedryl and Zyrtec, both to no avail. I would call your pediatrician ASAP. Good Luck, I know how awful it is to feel so helpless when your child is in so much pain.

My middle son had this happen twice but it was not associated with an antibiotic. I forget what it's called but the pediatrician said a virus can settle in the joints sometimes causing them pain. He had me give him ibuprophen to help with the joint pain.

As one of the other posters suggested, I would check with the ped about possible serum sickness. My daughter had a reaction to augmentin (which is amoxicillin-based) last spring, and had hives for 5-6 days, and joint pain for three weeks. She took prednisone for about a week, along with benadryl and ibuprofen/tylenol for the entire three weeks. It was awful!

what's the name of new antibiotic?
amoxicillin is not known to cause joint pain. in fact it is the most useless antibiotic out there and should not even be given to children with ear infections.
make sure you follow up with ENT regarding eardrum rupture. it should heal within 1-2 months and if not a surgical procedure will be needed.
also the middle ear is exposed now due to the rupture so make sure you use earplug during bathtime.

My children and I have had allergic reactions to amoxicillin. We had hives and welts but I don't remember any joint pain with it. I hope he feels better soon!
