Blisters with sclerotherapy
I think you may be particularly sensitive to whatever sclerosant was used to treat you or the concentration may have been a bit high. No matter how good the injector, a tiny amount of sclerosant will leak out of the vein to the surrounding tissue. Normally, it causes a little swelling like a mosquito bite but in your case it has caused blisters. You can consider a lower concentration of sclerosant or different sclerosant altogether after these blisters have completely healed. Alternatively, assuming the veins feeding the spider veins have been closed, you could try laser sclerotherapy or Veinwave.
Blisters after sclerotherapy
I am not certain why you got those blisters. My first thought is a reaction to tape that may have been used. I am a bit confused though about your comment about steri strips. I do not know why steri strips would be used for sclerotherapy, so perhaps there is more to your case. Also, do you know what sclerosing agent was used for your sclerotherapy? You may have had an unusual reaction to that. I agree with keeping the blisters clean and letting the open up themselves. I would expect them to eventually heal without significant scarring.
