My grandpa is having this problem since last 1 month. He suddenly got the problem while walking. He had lower back, thigh and leg pain while walking. After some days he also got fever so we consulted doctor and done blood report. In the report
CRP level was high around 49 or something so doctor gave him medicines and after completing dosage of medication he has no longer fever. But he still has problems while walking. We are confused what's happened to him. Please note that he has been chewing tobacco and smoking since 50-55 years. Please give some advice that what should we do.
