Reaction to Methimazole, doctor wants to skip PTU

Hello all, I guess I’m just looking for some advice / experience of people who have already been through this.

I have been experiencing symptoms of hyperthyroidism since 2023. TSH was trending low and my PCP said that no treatment was needed because my t4 and t3 were within range. I was pretty much left to suffer through the symptoms for 2 years. I lost my job and my relationship because it got to the point that I could not function as normal human being anymore. I finally said enough was enough and begged my doctor for a referral to endo. Endo ordered me an RAIU scan and it showed that my uptake levels were more than double what they should have been. I was out on Methimazole and had an allergic reaction (joint pain) and was quickly taken off.

In my head the next step was PTU, but my doctor completely wants to skip over that and is going right to RAI. Part of me feels relief that this nightmare might be coming to an end. But part of me feels like I should try everything before making permanent decisions… idk I am kinda at a loss.

The only thing that makes me hesitant to try the PTU is the reaction that I had to Methimazole. It’s just a lot to process right now and I’m not sure what to do.

Any input is greatly appreciated.

TLDR, had a reaction to Methimazole and doctor wants to skip PTU and go right to RAI or Surgery. Not sure what to do…
