Obviously it's a muscle sprain. Take rest and stop gyming

Dear Mr.30, as per your question, those pain are usually due to soft tissue injury & muscle strains. first you need to do is give rest that part (with support/skip gym),ice application if it is not very chronic, & visit a clinic for thoroughly clinical assessment. as it is not related to your bones so plz don't go for any supplement without a prescription from doctor/ nutritionists. it may have its side effects as well. Hope it will help you. for more details visit www.proactivephysio.in
