Sir, I am 59 year old male, weight 91 kg suffering from old back pain due to narrowing of space between L4-L5 and L5-S1. One month ago when I was on tour I had to travel on foot for some considerable distance with luggage. After that I am suffering from sensitiveness on the upper surface of right foot. Sensitivity covers space between right foot toe and ankle joint. I also feel muscle pain below knee in the same right foot. Also feel pain in right leg in movement. Now taking NERVIJEN P one can daily. Feeling some relief. From one day before feeling mild pain in bone below knee. No other ailment. Pl suggest remedy.
