Reoccurring stye help

I got my first stye in February. It never fully went away, though it did get better. Then it got bad again in March, and then one again, got better. But I could still feel the lump of it on my eyelid. I went to the doctors, they said it’s not a big deal and not to worry. I went to the optometrist and had an eye scan and they also said everything was fine and it’s just some blocked glands under the eyelid. It’s now April and my stye is bad again, I put chlorsig under my eyelid every night. It gets better through the days but as soon as I wake up my eyelid is swollen. I also have bad headaches on that side of my head when I wake up.

Can anyone suggest anything? If the doctors think it’s no big deal and can’t give me anything, and I’ve tried warm compress, tea bags, eye drops, can anyone suggest what to do next?
