Help I’m sick

So I got this weird thing where I’m immune to painkillers like acetaminophen and ibuprofen so I can’t take painkillers cause they don’t work (aleeve does but it gives me migraines after) and I was wondering if there’s anything I can do to get rid of a headache and body ache. I don’t like tea or soup and got ibs so I can’t have that sleep medicine or cough drops cause it has high fructose or sucrose or a sugar that’s a bit much for me. Just wondering if y’all got any answers for me since google doesn’t believe me
