I had two horrible back spasms - one a sharp pain like a dagger going from one side of my lower back to the other side and the next one 2 days later like a crack right in the middle of my lower back then 3 days later my right hip radiated excruciating pain at the top of my right thigh with any type of leg movement, with no radiating down my leg. Should I let time take its course and let it heal or do you feel it necessary to see a specialist? It has been 2 weeks since the onset but is getting better.
