Welcome to the forum

Sorry to read of the difficulties that you are having with injections sites. As
@Inka says with a pump you are only putting one needle in you every two or three days, as opposed to four r more each day on Multiple Daily Injections. So a pump may well help you, although you will need to ensure that you move your cannula sites systematically.
Any pump takes a bit of time to get used to and it does require a bit of time in setting it up to suit you, but it is well worth the effort.
Basal
The pump replaces your background insulin with tiny amounts of quick acting insulin which are delivered automatically throughout the 24 hours. You can adjust these to match what you need hour by hour. For me this eliminated virtually all night hypos, and the consequent bounce afterwards.
Bolus
You have the option of delivering bolus injections in a variety of ways, all at once as with an injection or over a period of time (great for a meal with more fat in, which means ’difficult‘ meals become easier) or a combination of these two.
Flexibility
You have the option of turning your basal insulin up or down for any length of time. I found this great and meant that I could be a lot more flexible about exercise, and just needing to know what you are going to be doing about an hour before.
I could go on about how I love my pump But will just say that if you have been offered one, and are willing to put the effort in at the start it can make life with T1 a lot easier. Quite a few on here have found it hard to get one so it is great that they are offering you this. Do come back with any questions that you have.
