Just reading your post after looking up searing pain in little finger and wrist and thinking im gona have to take more pain meds. Yes you are right it does effect everyone differently but the one factor that is the same for everyone is Pain and I find it shocking that you are not given meds to allieviate your pain. I would not be able to function without pain relief. I take Codiene/paracetamol 30-300 2 or 3 x daily, depending how much pain im in & Pregnabalin 75mg am & somtimes another at lunchtime & then 2 at night. Amitriptyline 10mg am & 50mg at night. Also Quinine to help with cramps. I also have pain management and a team of guys at the hospital that offer Tai Chi, help with diet & weight, swimming etc. My doctor is brilliant. So yeah lots of help available & pain relief medication. Not that it always takes the pain away but it takes the edge off it so I am able to get through my day & function a bit better.
I find hot stone massage or aromatherapy massage really help and heat.
Hope this helps answer your question.
Also hope you get something to help your pain.
