What is the safest and most effective painkiller I can take for muscle pain and weakness in my calves, thighs, and hands, considering I have irritable bowel syndrome with constipation (IBS-C), slow bowel movements, and am currently taking Normaxin, Unienzyme, Prothiaden, Cipcal, Cipcal D3, Evion, Nexito, Pregalin, and Cremaffin Plus?
Given your current medications and slow bowel movements, avoiding strong pain relievers like opioids is crucial, as they can severely worsen constipation. The safest first-line option for you is paracetamol. It is gentle on the stomach and does not slow your bowels. Since you are experiencing muscle weakness and taking medications like Pregalin, Prothiaden, and Cremaffin Plus, it is very important to consult your doctor.
