<s>[INST] last 2 weeks I have mild (tolerable) pin pricking pain below my toe ( not the heel part) on both my feet. I stand 5-6 hours a day at work and it does not help. I am not diabetic and I am 60 years old,male. No other symptoms. I had 2 robaxin 5oo mg left from my back pain (2 years ago) and I took 250 mg twice a day for 2 days and for 3-4 days I did not have any pain at all????? [/INST] Hi, Thanks for providing the brief history of YouScience you mentioned your symptoms you have, and you have to stand for 5-6 hours a day, also you tried self-medication which didn't work. What it looks like to me is the nerve getting irritated at the lower spine region for which you are feeling these symptoms of pin pricking. And also you had the back pain issue in the past as well which is making me think this. Since the symptoms are not too big and tolerable for you, I think you can be fine with some exercises for which you can meet a physical therapist and learn from him. Or either you can do some exercises for strengthening the core and the spinal muscles. By this the symptoms should stop. Also, whenever the smallest things start from the spine, one should keep continuing the core strengthening and spine strengthening exercises for long term to avoid major injuries. Feel free for anymore queriesRegardsJay In Chat Doctor.  </s>
