Hi Doc, I Had A Wrist Fracture In March And

Hi doc,

I had a wrist fracture in march and got to know about it in April and had a cast for 6 weeks. It healed but after removal of cast with a 2 Months gap a cyst formation appeared on wrist which I thought was because of torn ligaments or muscles but it didn't go away. I got a MRI where it shows erosion in the wrist. I had ESR at 32 and negative RA and Anti CCP. My doc said its bone TB. Another doc has asked to get my bone scan done. Should I go for it or should I continue with my tb meds. I have mild fever, chest pain,stiff neck,dizziness and pain in hand.
Why bone scan is required if MRI is done. Am I suffering from cancer. Pls let me know. Doctor has also put me in a cast.
