Lymjev is known for stinging and swelling, it’s the additive that makes it faster acting— however this fades over time, but I’ve always had a swelling at infusion site typically goes after a few days
Lymjev is fast acting humalog, Fiasp is fast acting novorapid.. so no point trying fiasp if you don’t get on with novo rapid
Humalog may be ok if it’s available again
There are other new name insulins available but they are just generic brand humalog or novorapid
Failing this you can go to older insulin like humalin
But as I say I’ve always had a lump form no matter what insulin…. For me the first 2 months of lymjev would sting like hell, but I typically don’t feel it now
