When will my upper arm feel normal after mastectomy with axillary clearance?

Thanks @Abbydog for bringing this up and others for your feedback. I had double mastectomy and ancillary clearance last Thursday and there is certainty a mixture of numbness, swelling and possibly some nerve pain in my upper arm. I gather it will take time to settle. I expect there is fluid retention too and I notice weird sensations / small spasms in around the ancillary area and upper back.
