Here’s my approach, much of what Shiftkicker and Nikki have said already. Consider some or all of these modalities:
1. ROM and stretching maybe 2-3x daily. Best if done after a hot bath/ shower or using a heating pad to warm up stiff muscles. Start slow and easy with any ROM and stretches.
2. PT to help with above
3. Consider X-ray of any painful or swollen joint regions.
4. NSAIDs like Ibuprofen judiciously, taken with food. Watch for stomach upset, fluid retention, dark or tarry stools. Stop if any concerns.
5. Consider Baclofen or Tizanidine if there is spasticity.
6. Gabapentin or Cymbalta or Lyrica sometimes are useful for chronic non inflammatory pain.
7. CBD oil with or without THC.
8. Massage
9. Acupuncture
10. If it’s one or two areas such as hips or shoulders, consider a Lidocaine patch 12 hours a day (to include sleeping hours). Other pain patches such as Capsaicin, NSAIDS also may help.
11. Opioids are a last result unless in or nearing terminal stage of ALS.
