Spine TB and surgery for abscess removal

I had lower back pain for more than a year. It started because I used to play cricket and in x rays it showed nothing, so assuming it's muscle pain I did everything I could like excersize, yoga, medicines, physiotherapy but the pain and stiffness sustained. One thing which was wierd is that I used to feel stiffness and pain while sleeping and sitting(rest pain- symptom for spine tb) but I could jog and walk easily without pain. Finally did MRI and found out abscess in my spine(l4, l5). Doctors said that the abscess is approx 2 months old but I had pain from last 1 year. Had a surgery to cut down the pain and also to collect the abscess as sample for drug tests. Now it's 3rd month running and still my surgical wound hasn't healed yet, there's puss comming out from the stitch marks. Doctor said it would eventually stop when medicines would start working. My medications include ethambutol hydrochloride and isoniazaid tablets, pyrazinamide tablets, rifampicin tablets, other vitamin tablets. And I'm still awaiting my 1st line and 2nd line drug test report
