Lasik 4 times done & was told no more surgery because it will regress? +0.5 both eyes after last surgery, I'm 6 months out & 22

I had -5 and -4.5 in eyes. kept doing the surgery because I was getting astigmatism and nearsightedness back of either -0.75. The last procedure I had a -0.50 astigmatism both eyes.they did the surgery again.Im +0.5 They say that it will go away on its own in another 6 months. I have strain watching tv and reading, in the morning my eyes start to hurt than into my forehead. I saw 2 ophthalmologist and they say symptoms are illogical maybe its migraine. They said I dont need glasses, no surgery
