It's probably worth briefly describing what sciatica is. Usually its main symptom is nerve pain, that seems to arise chiefly from the back of the thigh. Though it's generally not caused by thigh damage. Instead it is caused by damage to, or misalignment of, the lumbar area of the spine; where the root of the sciatic nerve is situated. This means that there is pressure on the nerve and the sensory transmission to the brain is interfered with. Because the main sensory area of the sciatic nerve is the posterior thigh and not the spine, the brain then mistakenly believes that the problem originates in the thigh. The sciatic nerve also innervates the muscles of the posterior thigh. For example, nerve impulses that stimulate the contraction of the hamstring, are delivered by the sciatic nerve.
So, anyway, I think it's possible hamstring damage can contribute to sciatica; and vice versa. I suspect that the main way it could contribute, is that with hamstring damage, the person is not going to be walking normally. Instead, they're likely to have an unbalanced stride, which could contribute to a misalignment, which in turn pressures the sciatic nerve. I guess that it could work the other way. With sciatica, the person may not be getting accurate information about what the hamstring is doing and/or there is erratic innervation of the muscle. If this means that the hamstring is not functioning correctly, then this could lead to a strain?
As far as treatment goes, I really don't know.
