Welcome to HealthCareMagic,
can cause damage to Tendons, but it is not a rule. Adverse reactions are mostly mild to moderate only. Severe adverse effects can occur occasionally. If you are not feeling any problems with your joints or tendons, you shouldn't worry. If exercise/games cause any problem to your joints & tendons, consult an Orthopedic Surgeon for examination and opinion. For urticaria
you should get Stool, TEC & VEC test done and consult a Skin Specialist.
Hope you found my response to your query informative and helpful.
With good wishes,
Dr.Chandra Shekhar Sharma
