Deltoid is an important one but you can live without getting it fixed. One of the most important things with repairing muscles like that is limit the sugar intake!! Sugar slows down healing of these things so it sucks to deal with it but eliminate sugar as much as you can and it should get better in a good manner.
I can’t speak much of it though because I partially tore my bicep tendon years ago but never got it looked at :D. It’s largely back to normal except I can’t do pull ups because of the strain it puts on it. I haven’t done a pull up or attempted in a while but when I was going to the gym all the time that was my biggest limitation. These things do heal, we just have to be careful with them.
In a couple weeks, I figure around maybe July you should do some light physical therapy to help give it some strength back. Keep that up for a while and you should be largely back to normal! PT exercises for deltoid are super easy too, can get a resistance band off Amazon for like 5$ and that’s all you need. Look up a few videos and bam, you save a trip to the doctor.
Oh that is good to know. By limiting my movement these last days I have noticed a difference already. It is not that horrifying deep ache anymore and I can move my arm in a wider range without screaming. I have a resistance band or two from previous injuries so I think you are right. I will check out a couple of vids and see what I can be doing to help it. It is a bummer now that you mention pull ups as that is one of my mainstays in the gym as it is sog good! We do have one of those ones that assist your weight though so I can pile the pounds on that to make myself light when ready!
Till then, easy does it!
