I have today been diagnosed with neck TB, in addition to the antibiotic regime I will be prescribed over the coming months, what advice can you give regarding the kind of things I can do to aid my recovery? Will I be able to attend the gym normally? Will I need to see a nutritionist?
For tuberculosis first you have to start anti-tuberculous Chat Doctor.  In addition to AKT, you have to take high protein diet and some protein supplement like protein ax powder 2 SF twice daily with milk to boost up your immune power, to gain weight and to recover faster. You can also have some multivitamin like tab biplex-forte or tab spray once daily for weakness. Take balanced diet as it is also very important. If you are following all the things properly than no risk in going to gym also.
