Hi, I a feeling really unwell , I have lower back pain,I feel very sickly and lethargic. I had achilles surgery in November and gastrocnemius lengthening,and I am waiting to go back in for more surgery on my heel,as the surgery hs not been a complete success,. But the last few day this pain in my back has completely wiped me out , I am currently taking 1800mg of gabapentin and tramadol 100mg 3 x a day, my back had been fine upto 4 days ago and now this pain is unbelievable. What can I do to ease it?
