Im so sorry for your pain. Im also newly diagnosed and i can only tell you what i am on. I take Amitriptyline at night. Its an anti depresant that is also used for nerve pain. Its really helped me and might be good for you to also help with sleep and anxiety. During the day i take over the counter Codene/Ibuprofen to take the edge off.
Also ive personally found Physio therapy a great help. At home i use warm epsom salt baths and heat packs.
People have also talked about going to pain clinics for their meds. They might have a better idea of how to treat you.
Hopefully someone on here is in your area and can point you to the best doctors in your area. This is much easier to approach once your pain is under some sort of control.
I really hope you get the relief you need. the people on this forum are fantstic and supportive of us newbies.
Good luck. also once you get pain relief try to keep your foot moving as much as it allows. Ive found its a "use it or loose it" kind of situation.
