The good news is knowing exactly which tendons are involved doesn't really change the rehab process too much. Tendonopathy is not something that generally goes away quickly or with time off. You need to continue training with it but managing the loading to the area to nudge the pain. If you do this correctly at the 3-month mark, you will probably be in a much better position than you are now. Avoiding it and pushing through it don't very well as strategies. I would hold off on the front raises if they are particularly sensitizing. I would start benching, pressing and using the lat pulldown now with light weights using a controlled tempo through whatever range of motion you can tolerate. You can use pins/safeties in the rack to gradually increase your ROM if things are very sensitive. If you can do a full ROM just start light with higher reps (10-15), train every 48-72 hours, and gradually increase the load and drop the reps until you are back doing heavy 3x5s. I would alternate bench and press each session.
