Hi there. My name is Vinay. I'm so sorry your having difficulty caring for your Mom. Let me see if I can help give you some options tword her pain relief.
From the sound of it.. you actually have 2 different pain issues that need dealing with..
1) is the "neuropathic" (nerve related) pain from the shingles (the areas that hurt because of that are going to be following along a single nerve track on the body, they won't generally bother the joints).
This kind of pain is caused by a single
spinal nerve that is being irritated by the same virus that causes
Chicken Pox (we never really get rid of it when we get it as kids.. our immune systems just beat it senseless and it hangs around inside our nerves waiting for the immune system to weaken.)
Treatments for this involve drugs like
Pregabalin (Lyrica) and Gabapentin (Neurontin) and yes.. they have side effects.. Have personally seen the confusion some patients can get from a single dose of lyrica.. so i'm happy you discontinued..
The next steps in the management of this kind of pain are trying other drugs... like neurontin.. or using stronger and stronger narcotics... luckily.. the disease shingles is generally self limiting and your mom will not have to be on these drugs forever.
2) Is the arthritic pain that i'm betting hits her joints and her back.. Low grade anti inflammatory drugs like asprin and ibuprofen are great for occasional relief. There are some long term
COX-2 inhibitor drugs available by prescription that you can talk to her doctor about. I've never been very happy with any of them myself.. But they are an option you can discuss.
Further management of this kind of pain also depends on lifestyle.. Do you think Mom could stand to lose a few Kilo's?
Weight loss is known to bring down a patients arthritic symptoms very effectively and very quickly. Secondly look at habits... smoking and alcohol consumption tend to worsen inflammatory issues (arthritis is chronic
joint inflammation). Exercise is important too! Low impact
aerobic exercise (think poolside or water based aerobics, walking, tai chi etc) have been shown to help arthritic pain.
I hope this information can help you in managing moms pain once and for all. If you feel you need any clarification or that I can help you further, feel free to contact me through HCM.
Thank You
Vinay
