Sounds like you may have lymphodema in your arm , which PT would be necessary for that.
I was supposed to have expanders put in at the time I had the double mastectomy. When I woke up in recovery the nurse told me I had implants. Sure enough my plastic surgeon chose not to put expanders in and put small implants in, the size that my skin would accept.
Needless to say I've been so emotional over his decision, I'm so sad and mad and confused why did he do that 😭
In my healing process I ripped open both incisions and pulled out a drain tube. It was months very very long process for my incisions to heal. Finally after 3 months he offered to do fat grafting from my belly to my breast to fill in the ripples and dents and gaps. While I was in surgery he said he was able to put in a little bigger implants implants than he had before. I'm a little over a month out from that surgery. I'm not any bigger and where the fat grafting was placed I don't know. Basically had another surgery but no difference.
I don't know if you would consider that a exchange but the healing process has been much easier and faster. My incisions have completely healed and after a week basically no pain and fill range and movement. I'm hard as rocks and with clothes on look flat chested.
I definitely would check with your doctor about the pain and if you do have lymphodema you need to get on that right away.
Hopefully you have a better PS than me and can get something for your pain and heal quickly. Please let your doctor know how you're feeling. Best wishes for everything to get better. ❣️ Hugs

Ask for PT referral you would not want your shoulder to freeze. I have been down that road before and it is just painful in its self. You've got this and tears are allowed 🌺 we all have our moments for sure. We are all in this together my Pink Sister. Here for you anytime 🤗

I didn't have the same surgery. I had 2 lumpectomy surgeries and they did go under my arm too to check my lymph nodes. I did have restricted movement in it also. Please contact your doctor. Physical therapy helps.

I haven't had exchange surgery, but it is natural to have some pain after any surgery, and it should be getting a little better each day as incisions heal. It is not uncommon for nerve pain to develop after breast surgery as nerves are typically cut in the process of the procedure/ Nerves tend to heal slowly and erratically, and if so, there may be nerve pain. Your doctor should be able to prescribe a nerve medication such as gabapentin to help ease the pain you have with healing. Another thing that often helps with nerve healing is physical therapy. Often a physical therapist can suggest stretches and exercises to help affected muscles and nerves recover and regain their range of motion with comfort. Speak to your doctor about nerve medication and a referral to physical therapy so you can heal the best way your body is able to do! Hugs and prayers!!

I agree with the other ladies comments. PT will help you prevent frozen shoulder and relax the muscles.
My pain after surgeries, chemotherapy, radiation and infection did not ease up until after over a year. I also had PT for 10 sessions, wore tight sport bra (to help with the swelling) at night and do my exercises 2x a day. I’m still a little bit sore to touch and taking Gabapentin to ease the pain. This is my own experience. I can’t believe it too that long for the pain to ease up.

I would still speak with your surgeon. They should be able to help you. Everyone react and heal differently.

Sending prayers to ease your pain and doctor help you with your suffering.
