Hi..
Thanks for writing to us..
The symptoms can be probably due to medication side effects causing allergies..
Burning of tongue can be due to
dry mouth which can be commonly seen with such medications causing inflammation and burning of tongue..
Consult an Allergist and get allergy testing done..
Skin prick test,
patch test and RAST test can be done.
If it is due to medicine then dose reduction will help in improvement..
If it is due to some other causes then it will be excluded from your diet.
For allergy anti allergics like
Benadryl or Levocetrizine can help..
For burning tongue you can reduce burning with
Lidocaine mothwash, suck ice and continue taking Vitamins.
Apply
Caladryl lotion on lips and face to soothe the burning and itchiness..
Hope you get relieved soon..
Regards.
