Hi,
The health issues does look like a long-term or chronic in nature. It is interesting indeed that Naisargika Aarogyakaraka Sun/Ravi is at logger heads with Rogakaraka Mars/Kuja. They engage in a planetary war or Graha Yudda and in the process Mars/Kuja has been torched. Rest of relevant details have been shared by respected TKC and I’d encourage the querant to consider performing Navagraha Shani Homa and Dhanvantari Homa.
Take care…
