Hello Bernie tell your mum it will get better in time I'm 80 yrs also and had it for 12 weeks and the best pain relief I use is Tramadol and Gabapentin muscle relaxer , It's taken me the 12 weeks to get an appointment at our hospital for them to tell me they will give me an injection in a further 5 weeks and they will get in touch in MARCH for a Tens Machine ,Makes you wonder about our NHS ,It frightens the life out of you getting sick in old age Anyway Bernie tell your mum it will get better it's just a slow old job
