Thanks for your query. TdaP should not give rise to the type of reaction which you have described. Secondly, there is never a need for an antibiotic for vaccination
induced reaction. As the high fever
responded to antibiotic it must have been some other reason.
As you doctor has mentioned that the pain is due to tendinitis
, I suggest that you follow the doctors advise and take anti-inflammatory medicines and later take recourse to physiotherapy
Wishing you an early recovery.
