Need help: I'm in pain everyday and don't know what to do

23F. PMH of PCOS and asthma. In January, I went to the ER with severe pain in my upper left abdomen and blood in my stool. I also had pneumonia and COVID at this time and was told the reason for this pain was due to a bleeding ulcer caused by all the meds I was on.

Fast forward to March, I'm still having pain in my stomach. Not unbearable as before but still enough to cause discomfort everyday. The pain is sharp and constant. Gets worse when I don't eat. I had a gastroscopy done and was told I had a hiatal hernia. No treatments given except some PPIs.

Now it's mid-June. I still have pain in my stomach every single day. It sometimes affects what I'm doing and I have to stop and rest for a bit. I also had an ultrasound and some blood tests done but I'm assuming that's all fine because they didn't call me back. I only saw online I had low ferrtin (lower than last year and I've been taking iron supplements, not sure if that's even related to this)

I can't get an appointment with my gastro until the fall but I've already been waiting so long and can't take this pain anymore. I've also gained about 10 pounds but haven't changed my lifestyle at all. I feel bloated all the time too.

Does anyone have suggestions about what I should do? Could the pain be caused by anything else?
