self diagnose with sciatica pain

Haidee • 30 yrs old- female
I'm in so much pain on my right buttocks & it travels down my leg. I use a heating pad, do stretches, take the occasional Tylenol but the pain is just getting worst. Doctor wants me to take a week off from work to rest but I cant do that... i just started & it would be an unpaid week 😰 anyone else been through it? 27 weeks today
