I have long term back problems, and have had three spinal surgeries in the past. I have been left with walking difficulties and severe pain, last night I started to feel pain in my left calf, about 3 or 4 inches below my knee. The pain gradually increased through the night, keeping me awake for most of it. It eased off this morning, but is now starting to build again. About three months ago a similar thing happened, though the pain wasn't so severe, and it went away after a few hours.
There is no redness or swelling, but my leg is really tender to the touch, and is also painful when I stand up or walk.
Is this anything to worry about please?
